Recent Trends in Work Conditions

Money isn't everything. When choosing a career, most people also consider the work conditions. Will the job be mainly indoors or outdoors? Will it involve a lot of time pressure or high-impact decisions that add stress? It's nice to be able to choose work conditions that agree with you, but sometimes the jobs that are available do not offer exactly what you want, so you have to make compromises if you want to earn a paycheck.

As the economy changes over time, there are changes in the salience of various work conditions that people deal with on the job. I decided to identify recent trends in work conditions by examining recent data about occupations and about the changing levels of employment in occupations. Which work conditions are becoming more prevalent and which are receding?

Here is the procedure that I used to track several work conditions:

  • I used workforce estimates for the years 2006 through 2012 from the Occupational Employment Statistics survey of the BLS. Note that this covers most but not all workers; self-employed workers are not included.
  • For each occupation, I multiplied the workforce size at each year by the numerical ratings for various work conditions in the O*NET database (where they are called Work Context elements).
  • For each year and for each work condition, I summed the products for all occupations and summed the workforce sizes of all occupations.
  • For each year and for each work condition, I divided the sum of products by the sum of workforces to get an overall quotient that indicated the level at which that work condition was significant for the nation’s workforce during that year.
  • Finally, I graphed the changing levels for each work condition.
Note that each chart below uses a different vertical scale, and that this scale is selected to emphasize the vertical movement of the curve. If I had plotted all the curves on a single chart, the vertical movement of some of the curves would not have been as evident. I'm more interested in the direction of movement than in the absolute value of the movement.

The first two charts show the trends for outdoors and indoors work. (Actually, in O*NET, the specific work conditions I used were "Outdoors, Exposed to Weather" and "Indoors, Environmentally Controlled.") As you might expect, the two curves are almost mirror images, and the general trend is away from outdoors work (although there has been a leveling-off in the most recent years). One factor contributing to that trend is the increasing mechanization of agriculture. Another factor is the decline in construction work that followed the collapse of the housing bubble.





You may wonder why the two preceding curves are not exact mirror images--why indoors work falls off very slightly during the recovery even though outdoors work does not pick up by a comparable amount. I found that the slight dip in indoors was offset by slight increases in work done in interior environments without climate controls (such as the jobs done by some warehouse workers and mechanics) and in enclosed vehicles (such as the jobs done by transportation workers and many sales workers). These mini-trends reflect the job growth that happened following the Great Recession, in which office jobs did not return as fast as some skilled blue-collar jobs.

You can see more evidence of this mini-trend in the following chart, which shows the trends in sedentary jobs.This chart shows a curve almost identical to the curve for indoors work.


The trend in what O*NET calls "Degree of Automation" may surprise you by its downward slope. Isn't automation constantly increasing? Understand that the curve represents not the amount of automation being used but rather the number of workers whose jobs involve a lot of automation. Most employees in manufacturing have worked with automation for a long time, so when automation reaches the point that it eliminates a manufacturing job, that's one less automation-related job. An additional drain on automation-related jobs was occurring in the years 2006 through 2009, when many highly automated jobs were being shifted to plants in foreign countries.

On the other hand, you'll note that the slope has pretty much leveled off in the most recent years. I interpret this to mean that automation is not a threat as much as it is the new normal. It's getting harder and harder to find new ways to automate jobs, and the great bulk of automation-using jobs that can be shipped overseas already have been offshored. Nowadays we're actually seeing an increase in advanced manufacturing jobs.



If automation is the new normal, what does this mean for you as a worker? It means that you need a high level of skills, either for doing the things that automation can't do (making sophisticated judgments or using people skills) or for doing the technological work of creating and programming automated equipment. And this is true no matter whether your work is indoors or outdoors, standing or sitting.

How Work Tasks Responded to the Recession

In a recent blog, I crunched some data to see which parts of the nation’s workforce lost the most jobs during the Great Recession and which gained the most during the recovery. I created graphs that looked at the workforce two ways: by occupational group and by industry. This week I think it would be interesting to look at the kinds of work tasks (and, by implication, the kinds of skills) that lost ground or regained it during the recent downturn and upswing.

I created the four graphs below by this method:
  • As in the previous blog, I looked at changes over two pairs of years: 2007 and 2009 for the recession, and 2010 and 2012 for the recovery.
  • I used workforce estimates from the Occupational Employment Statistics survey of the BLS.
  • For each occupation, I multiplied the workforce size at each year by the numerical ratings for the 41 generic work tasks in the O*NET database.
  • For each year and for each task, I summed the products for all occupations and summed the workforce sizes of all occupations.
  • For each year and for each task, I divided the sum of products by the sum of workforces to get an overall quotient that indicated the level at which that task was important to the nation’s workforce during that year.
  • For the recession and for the recovery, I computed the percentage change in the overall quotient for each task, thus getting a measure of how much each task became more or less salient during the recession and recovery.

(I suggest you click on each graph to see it in a format that is big enough to read easily.)

This first graph shows the work tasks that lost the most ground during the recession. Based on the types of tasks that appear here, you can see that this downturn really deserved its nickname “the mancession.” These tasks characterize the manufacturing and construction industries, which were among those hardest-hit by the slump. Note how every one of these tasks bounced back during the recovery, but not enough to make up in two years of recovery for the erosion during the two years of recession.

But some types of jobs actually gained workers during the recession, and the second graph shows the work tasks that reflect this. These work tasks, which gained the most ground during the recession, characterize the education, health-care, and government jobs that were not fazed by the downturn. However, half of these tasks proved to be countercyclical—that is, they slid downward while the economy recovered. And even those that showed gains during the recovery did not match the gains they made during recession.



Like the recession, the recovery did not affect all kinds of jobs the same way. Some jobs actually showed a net loss of workers during the recovery, and the work tasks in the following graph are those that lost the most ground during this period. Note that every one of these did quite well during the recession, but they suffered (although not to the same extent) while the economy as a whole rebounded. These tasks characterize bureaucratic and clerical jobs, which have been hurt by government cutbacks and by automation.


The last graph shows the work tasks that gained the most ground during the recovery. Many of these tasks appear as “mancession” victims in the first chart, but two of them characterize white-collar occupations. It’s especially interesting to note the job security indicated by the steady growth of work that involves Selling or Influencing Others.

America’s Most Creative Cities and States

Many of the most promising careers involve a high degree of creativity. This is happening because in today’s economy, much routine work can easily be handed off to computers, robots, and offshore workers. A decade ago, it was mostly low-skill jobs that got lost this way, but computers have  become smart enough to make inroads into middle-skill jobs. For example, some of the research work of paralegals is being done faster and more cheaply by computer programs.

However, computers so far have demonstrated little ability to do truly creative work. To be sure, we have all seen haikus written by computers and similar machine output that seems creative. But an algorithm defines how such tasks will be accomplished, so the creative part of the process happens when the systems analyst or computer scientist devises the algorithm. As a result, the creative worker has some security from the threat of being replaced by a computer.

Offshoring is also less of a threat for a creative worker, because the United States still is home to many hotbeds of creative industries. They are geographically clustered, just as the energy-extraction industry is clustered in certain oil patches and coal belts. You can understand that petroleum extraction and coal mining need to be located where the resources are to be found in the ground, but why should creative work need to cluster? The urban theorist Richard Florida says that creative workers are most productive when they can collaborate, bouncing ideas off one another. And the communities where they tend to cluster for collaborative work tend to have research universities, a good communications infrastructure, nearby investors, a lively cultural scene, and tolerant attitudes. The United States has many communities that offer all the ingredients of this creativity-fostering recipe.

I decided to identify these highly creative geographical areas, not by looking for the presence of these ingredients, but rather by finding the presence of creative workers. To do so, I combined data from the O*NET database, which describes the characteristics of occupations, and employment figures from BLS’s newly-released Occupational Employment Statistics survey, which has estimates for May 2012.

Here’s the procedure I used.
  •  The O*NET rates occupations on the level of “Thinking Creatively” that they require. For each occupation, I multiplied this rating by the number of workers in that occupation within each metropolitan area in the United States.
  • Then I divided this product by the number of workers in all occupations in the same metro area.
  • Finally, I sorted the metro areas by this “creativity quotient” and ordered them from highest (San Jose-Sunnyvale–Santa Clara, CA: 3.38) to lowest (Ithaca, NY: 1.85).

As you might expect, these jobs tend to be concentrated in the Silicon Valley and in similar hotbeds of high-tech industries. Here are the top 20 metro areas where creative workers are clustered, listed with their creativity quotients:

San Jose-Sunnyvale-Santa Clara, CA: 3.38
Washington-Arlington-Alexandria, DC-VA-MD-WV: 3.31
Boston-Cambridge-Quincy, MA-NH: 3.21
Huntsville, AL: 3.21
San Francisco-Oakland-Fremont, CA: 3.20
Denver-Aurora-Broomfield, CO: 3.19
Austin-Round Rock-San Marcos, TX: 3.18
Hartford-West Hartford-East Hartford, CT: 3.18
Bridgeport-Stamford-Norwalk, CT: 3.17
Raleigh-Cary, NC: 3.15
Baltimore-Towson, MD: 3.15
New York-Northern New Jersey-Long Island, NY-NJ-PA: 3.14
Minneapolis-St. Paul-Bloomington, MN-WI: 3.14
Boulder, CO: 3.13
Atlanta-Sandy Springs-Marietta, GA: 3.13
Dallas-Fort Worth-Arlington, TX: 3.13
Albany-Schenectady-Troy, NY: 3.11
Charlotte-Gastonia-Rock Hill, NC-SC: 3.11
Seattle-Tacoma-Bellevue, WA: 3.11
St. Louis, MO-IL: 3.09

Here is a map that my friend Jeffrey Doshna of Temple University produced, using the data about metropolitan areas that I furnished:



I also used the same procedure to identify the states where creative work is clustered. On the map below, the darker the color of the state, the more creative work is concentrated there. (I couldn't find a colorable map with Alaska and Hawaii, but they would be among the very pale states.)

Real-World Data Showing Trends in Job Security

Nobody’s job is completely secure, but some jobs are more resistant than others to the ups and downs of the economy. I have written books and blogs on this subject and have also created a video about it. Now, here is some new, real-world data that provides additional insights into this matter. The data may give you some insights into what careers you might pursue or avoid.

Last week, the Bureau of Labor Statistics released estimates for employment and wages in May 2012. I decided to look at the changes in employment in various occupational groups over two time periods: the Great Recession, which for my purposes I define as the difference in employment between May 2007 and May 2009; and the recovery, which I define as the difference in employment between May 2010 and May 2012. I find these particular dates useful because they provide symmetry: Each is a two-year period, and the employment in all occupations decreased by 3 percent in the first period and increased by 3 percent in the second period.

This symmetry ceases when you look at specific groups of occupations, and that’s what makes the chart below so useful. (You can see it full-sized here.) Note that the bars indicate change in percentage terms, not in absolute terms. Keep reading below the chart for my comments on what it reveals.


As I noted, the workforce for all occupations, taken together, declined during the recession and expanded during the recovery by the same percentage. And some families of occupations show a similar behavior, more or less symmetrical. The Sales and Related occupations are a good example of how employment can fluctuate in response to how much disposable income consumers have and are willing to part with for nonessentials. The Building and Grounds Cleaning and Maintenance occupations and the Farming, Fishing, and Forestry occupations were probably responding to similar forces. Many of the jobs in these three categories are low-skill, and employers can lay off workers without worrying about how to replace them when the economy rallies. They lack security, but they have been able to bounce back.

There tends to be a higher level of skill among the Installation, Maintenance, and Repair occupations; the Arts, Design, Entertainment, Sports, and Media occupations; and the Architecture and Engineering occupations. Nevertheless, they show similar symmetrical behavior and illustrate how even some middle-skill occupations are sensitive to fluctuations in the economy. It’s interesting to note that among the Architecture and Engineering workers, the occupations that continued to decline even during the recovery tended to be either related to construction, which was especially hard-hit by a recession set off by the explosion of a housing bubble (for example, Architects, Landscape Architects, and Surveyors), or were at a middle-skill level at which workers could be replaced by automation (for examples, various kinds of drafters and engineering technicians). The high-skill engineering occupations tended to recover.

Among asymmetrical occupational groups, some lost workers both in the recession and in what should have been a recovery. One of the most extreme examples is the Construction and Extraction occupations, which were hurt badly by the overbuilding that preceding the recession. The good performance of the petroleum industry has been unable to offset the many job losses in this field. (Nevertheless, the long-term outlook for many construction occupations is considered good.) The non-recovery of the Office and Administrative Support occupations cannot be blamed on a similar sustained slow-down in business activity—for a contrast, look at how well the Business and Financial Operations occupations have recovered. Instead, the continuing job loss in this field is explained by the expanded use of office automation. Again, the middle-skill and especially the low-skill jobs are unlikely to come back.

Other asymmetrical occupational groups achieved some expansion during the recovery, but much less than what would be sufficient to restore the recession’s losses. Good examples are the Production occupations and the Transportation and Material Moving occupations. Both of these fields actually recovered quite well from the recession in terms of productivity but did not replace the large number of low-skill workers who were replaceable by automation. (Offshoring was also a major factor for Production jobs.)

A fortunate few categories actually experienced workforce growth during the recession and sustained this expansion during the recovery. These tend to be groups consisting mostly of high-skilled workers: the Management occupations; the Business and Financial Operations occupations; the Computer and Mathematical occupations; the Life, Physical, and Social Science occupations; the Postsecondary Teachers; and the Healthcare Practitioners and Technical occupations. The exception that is notable for the comparatively low skill of the workers is the Personal Care and Service occupations. This group is dominated by the Hairdressers, Hairstylists, and Cosmetologists; the Childcare Workers; and the Personal Care Aides—all of whom perform essential services that cannot be automated and are not easy to do without even during hard times. A mostly low-skill group comparable to the Personal Care and Service occupations is the Food Preparation and Serving Related occupations, which experienced only a very small loss in the recession. We Americans seem limited in our ability to switch from restaurants to brown-bagged and home-cooked meals, even during bad times.

Finally, several families of occupations exhibited what might be called countercyclical behavior: they gained workforce size during the recession but lost workers during what should have been a recovery. These include the Community and Social Service occupations and the Education, Training, and Library occupations. They are actually needed more during hard times than during good times, but because they are paid largely out of the public coffers, they tend to experience cutbacks a few years after the trough of the recession, when state and local governments have run out of rainy-day funds and stimulus support from Washington. They may be expected to recover as tax receipts start returning to normal levels with the acceleration of business activity, but the anti-tax climate that now dominates many parts of the nation is likely to continue to hobble these occupations. Something similar accounts for the lackluster recovery of the Protective Service occupations.

It may seem puzzling to find the Healthcare Support occupations showing countercyclical behavior, especially in contrast to the recession-be-damned growth of the Healthcare Practitioners and Technical occupations. Actually, most of the occupations in this group, with middle-skill workers such as Occupational Therapy Aides, Massage Therapists, Dental Assistants, and Medical Assistants, showed continuous growth during both time spans. What has dragged down this group as an aggregate is the nearly one-million-strong Home Health Aides, who have not recovered like the Personal Care Aides. Home Health Aides are low-skilled workers who are easy to replace when a fully recovered economy justifies hiring. Both of these care-aide occupations are projected to grow by about 70 percent between 2010 and 2020.

The take-away lesson from this chart is very similar to what I concluded in a recent blog about a similar but less-detailed chart: Your best bet is a high-skill job, or at least a middle-skill job that is difficult to automate (such as many in health care), because these not only pay well but tend to thrive in both good times and bad times. 

Our society has not yet devised a way to prevent future economic downturns. Nor are we able to agree on and apply what it takes to shorten them, as the experience of Europe (and, to a lesser extent, the United States) shows. Given that a roller coaster economy seems to be here to stay, doesn’t it make sense to pursue a career that has comparative security?

Update, following the 4/5/13 release of data from BLS: Here's a graph from the Washington Post site that uses lines instead of bars, a slightly different set of industries, and a slightly different timescale. But it shows the same trends.


Another update, because manipulating data is fun: This graph uses the same method as the bar graph above, but (like the Washington Post graph) it represents industries.

Sell Your Knowledge

I have blogged recently about how you can make a career move that leverages your knowledge of an industry in a new way: for advocacy or for standards enforcement. I call these “sequel careers” and have written a book, The Sequel, about making these career moves. Another popular sequel career is sales.

Although some sales workers start their careers with little or no knowledge of the industry in which they land their first job, your background in an industry or at least one product can be a great advantage in a sales career.

The basic function of a sales worker is to convince the buyer that a product or service meets the buyer’s needs. That means a good sales worker has a thorough knowledge of the product or service being sold, is able to determine what the buyer’s needs are, and has the persuasive skill to sway the buyer to value the benefits of the product or service. As part of the process of closing the sale, the sales worker may need to negotiate the price or at least make the case that the going price is fair. The sales worker also may need to discuss optional features, the mode of delivery, a warranty, or other terms of the deal.

In some companies, the sales manager identifies likely customers by doing research, but sometimes this is done by sales workers. Likewise, an account manager may handle the task of making follow-up phone calls to verify the customer’s satisfaction, but often sales workers do this as well. Sometimes sales workers modify the product at the customer’s site as needed or train the customer’s staff to use the product, but for a highly technical product, this task is more likely to be handled by a sales engineer.

Sales workers usually need to keep track of new products and competition. They may visit trade shows and industry conferences. They attend sales meetings at their company to review their sales performance and learn about current sales goals.

For working in sales, it helps to have an outgoing personality and be able to get along with many kinds of people. One of the satisfactions of the job is the contact with people, but clients sometimes can be demanding. The work may require a lot of travel. Sales workers are often under pressure to meet a sales quota. Sometimes their income is based partly or wholly on a commission.

Most sales positions have no formal educational requirements. Workers need two kinds of knowledge: knowledge of sales technique and knowledge of the product being sold. Employers may train sales workers in both. For example, a manufacturer may rotate sales trainees among jobs in plants and offices to learn all phases of production, installation, and distribution of the product. Other employers offer formal classes and on-the-job training under the supervision of a field sales manager.

However, a good background in either or both kinds of knowledge will improve your chances of getting hired as well as your success on the job. Employers sometimes recruit sales workers from the end users of their products because these experienced users are familiar with the benefits of the product and the ways to get the best use out of it. Experience like this is particularly valuable for landing a job selling a scientific or technical product, although a bachelor’s degree in a scientific or technology field is another way of qualifying for such a job. If you’re a knowledgeable user of a product, you might consider approaching the vendor about a sales job.

Sales engineers usually have a bachelor’s degree in engineering, but some who hold this job title are knowledgeable about science or technology without being engineers. Usually they learn their skills by being teamed with an experienced sales worker, and they often continue to work as a team with someone who is more skilled with sales technique and less knowledgeable about technology.

Knowledge of a particular industry may give you an advantage in a job selling investments, commodities, or insurance related to that industry. Brokers and investment advisors must pass an exam and register as representatives of their firm with the Financial Industry Regulatory Authority (FINRA). Similarly, those who want to sell insurance must obtain licensure for the particular type of insurance, which usually depends on taking specific courses and pursuing continuing education to maintain licensure. Check the regulations that apply to your state.

Career Advice Inspired by Bruce

“Foreman says these jobs are going, boys, and they ain’t coming back to your hometown.”

These lyrics are from a Bruce Springsteen song that sometimes brings tears to my eyes. The song is especially poignant for me because my hometown is only a few miles from his—in fact, we were born in the same hospital, less than a year apart—and I have seen the decay of many of the places that Bruce and I grew up in.

Of course, his song is not meant to apply solely to our native part of New Jersey, but also to the many neighborhoods in decline across America as the economy has undergone drastic changes. For me, the most stark reminder of this sea change is the graph below, which appeared in an August 2012 data brief (PDF) by the National Employment Law Project. The NELP bases the graph on an analysis of statistics from the Current Population Survey. The bars for jobs lost in the recession represent the difference in employment between the first quarters of 2008 and 2010; the bars for jobs gained during the recovery, the first quarters of 2010 and 2012.



What does this graph say about your career future? Try reading the graphic with the understanding that wages are roughly commensurate with level of skill. That means that the segment of economy showing the greatest impact of the Great Recession consists of the occupations requiring a middle level of skill. In numerical terms, these occupations accounted for 60 percent of recession job losses but only 22 percent of recovery growth.

The inescapable conclusion is that you are going to need good skills to compete for the greatly diminished job opportunities at a middle level of skill—or, ideally, to secure employment in a high-wage occupation—and to avoid a career among the many low-wage workers.

One thing the graph does not show is how low the compensation is for many of the jobs that make the lower bar as long as it is. Consider America’s fastest-growing job, home health aide, which is projected to grow by 70 percent between 2010 and 2020. The median hourly wage is $9.91, which amounts to an annual wage of $20,610. Of course, many of these aides work part-time, earning a lower annual wage and probably no benefits. It’s no surprise that 40 percent of aides are on public assistance, such as Medicaid and food stamps.

I’d like to have some hope that the plight of these workers will be eased by an increase in the minimum wage—which is by no means certain to happen—but federal minimum wage and overtime laws don’t apply to them because they fall into the same category as babysitters.

Okay, so what are the high-wage occupations that will have a lot of job opportunities? I divided the range of occupations covered by BLS into three income zones with an equal number of occupations in each. I drew from those in the highest one-third to create the following table with the occupations that have the best combination of job growth and average annual openings, as projected by the BLS. The annual earnings are estimates for May 2011; the estimate for Physicians and Surgeons is almost certainly too low, because it is an average of all specializations, some of which have earnings above the maximum that BLS reports.




At the end of "My Hometown," the song's narrator sings about a conversation with his wife about maybe packing up and moving south. But the song's ending leaves this question unresolved. It's true that some parts of the nation (some in the Sunbelt, but don't forget North Dakota) have lower unemployment than others. Nevertheless, I suggest that for most people, the way to cope with this economy is to move your skills northward.

Will Work-at-Home Work for Your Career?

I have blogged about the joys of working at home, but it’s time to revisit this issue. This work arrangement has become the topic of considerable discussion now that Yahoo’s chief executive, Marissa Mayer, has told all her employees to report to the office. Further piquing my interest was a research study that I found this week in which economists compared the productivity of workers toiling at the office versus those working at home.

Let’s look at the research (PDF) first. The economists, at Stanford and Beijing Universities, studied the output of call-center workers employed by a Chinese travel agency. The workers were randomly assigned to work either at home or in the office for nine months. Those working at home performed 13 percent better than those in the office, partly as a result of putting in more minutes per shift (a 9 percent difference) and partly as a result of making more calls per minute (a 4 percent difference).

But consider the reasons that Marissa Mayer cited for her decision to call the 200 work-at-home employees back to the office. According to The New York Times, “A memo explaining the policy change, from the company’s human resources department, says face-to-face interaction among employees fosters a more collaborative culture.” Having come from Google, where this culture was the norm, Mayer decided that the change in work rules was needed as part of an overhaul that would bring Yahoo back from its long decline.

I think her reasoning makes sense, despite the findings of the economists. The Chinese call-center workers have no need for communication or collaboration amongst themselves. They communicate with the people who telephone them. They can work well—in fact, better—in the isolation of their home offices than in a noisy call center. The Yahoo workers, on the other hand, are doing the kind of collaborative work that causes the high-tech industry to cluster in places such as the Silicon Valley and the Boston suburbs. The famous “idea factory” at Bell Labs in Holmdel, New Jersey, where so much of our present technology was developed in the 1960s, was laid out with a long corridor that encouraged engineers and technicians from different disciplines to rub shoulders and trade ideas as they made their way to and from the cafeteria.

The photo below was actually shot at Allied Chemical in 1967, and although it often is mistakenly identified as showing Bell Labs in 1966, it gives an idea of the same architectural thinking at work.


If the world were really growing “flatter,” in the sense that Thomas Friedman describes, there would be no need for Silicon Valleys. We all could work at home. But note that many of the jobs that can be done at home—and call-center work is an excellent example—have been moved overseas to lower-paid workers. By contrast, many of the jobs that will remain in the United States will need to be the kind of collaborative work that is much harder to do at home. For example, one of the reasons that manufacturing is coming back to the United States is that creative production that stays one step ahead of the competition demands that engineers and technicians work close to the factory floor—in close contact with its workers and machines—rather than send specifications to a plant across the ocean.

Besides the creativity that teamwork can foster, another factor that is driving collaborative work is the need to hold down costs. Even in industries that require hands-on work that can’t be done at home, workers are becoming more collaborative so that highly-paid specialists can focus on the tasks that require their level of skill and knowledge. For example, in the health-care field, physicians work in collaboration with physician assistants and nurse practitioners, to whom they can hand off various tasks, and nurses do the same with aides and orderlies. In other industries, a similar cost-cutting relationship exists between engineers and technicians, between accountants and bookkeepers, and between teachers and classroom aides.

What does this mean for your career? It suggests that work-at-home arrangements will be harder to obtain if you want to work in the kinds of highly creative and collaborative jobs that pay well and are not likely to be offshored. If you want to work at home, be sure to ask yourself why what you’re planning to do can’t be done by someone overseas.

There certainly are creative jobs—often niche jobs—that are not collaborative, can be done at home, and would be hard to offshore. For example, think of an editorial cartoonist, who needs to be immersed in the American political and popular culture. Or think of an advice columnist, who needs to be attuned to the shifting mores of our society. For jobs that do require collaboration, advances in technology such as Skype make it increasingly possible to simulate face-to-face collaboration from one’s home.

But the trend in America’s economy is toward on-site, collaborative work. Technology will allow more flexibility in our work schedules, with some work still possible at home, but much of the work in the best jobs will be in the office.
