Careers That Keep You Out of the Cubicle

Are you hoping to avoid the Dilbert work environment? Specifically, do you desire a career that doesn’t require you to sit at a desk all day? I have some suggestions for you.

Maybe you have an antsy personality. Something about you is not satisfied with sitting in one place all day. If you feel strongly about this, you don’t have to explain why.

On the other hand, maybe you favor an active occupation because you are aware that it would be better for your health. Researchers have linked desk jobs to increased incidence of back pain, eyestrain, obesity, and even colon cancer. One Australian study found that men who sit at their desks for more than six hours per day were almost twice as likely to be obese as men who sit for less than 45 minutes. An American study found that women who worked at a sedentary job for 14 years gained 20 pounds more than women who worked in the least sedentary jobs.

Whatever your reason is for seeking active work, that kind of occupation is harder to find than it used to be. The shift to an information-based economy has meant a constant increase in the proportion of workers who manipulate data for a living—and who therefore spend most of the workday sitting at a desk. Researchers have estimated that the percentage of workers in physically demanding occupations decreased from about 20 percent in 1950 to less than 8 percent in 1996. Even in offices, people are probably doing less physical work than they used to do in the days when desk workers cranked mimeograph machines, hand-collated documents, whacked staplers, carried memos from one room to another, and typed (and re-typed) on manual typewriters.

Fortunately, there are still plenty of high-activity occupations for people who prefer them. And these are not just menial jobs that are likely to be phased out as soon as someone invents the right kind of robot to do them. Many active occupations have good earnings and are expected to have good job opportunities. They allow you to use your brains as well as your muscles and involve the kinds of people and problems that can keep you interested in your work.

To identify these occupations, I looked at two measures in the O*NET database that indicate level of physical activity. One is a work activity measure called Performing General Physical Activities. It is defined as “Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials.” Every occupation has a rating between 0 and 7 on this measure. The other measure is a physical work condition called Spending Time Sitting, which represents how much the occupation requires sitting. (Despite the name, it is not strictly a measure of time.) This measure also uses a rating scale between 0 and 7, so I subtracted each occupation’s rating from 7 to determine the amount to which the occupation does not involve sitting. I then took the average of these two work activity measures to get an overall score indicating the level of physical activity—i.e., how much the occupation is not behind a desk. Then I removed the least-active half of the occupations and kept the most-active half.

This was still a large list, so to focus on the most rewarding occupations, I followed the procedures I use in the “Best Jobs” series of books. I eliminated occupations that lack economic data, those with a particularly dismal outlook, and those that pay only a pittance. Then I ranked the 340 remaining nonsedentary occupations three times, based on these major criteria: median annual earnings (May 2011 estimates), projected growth through 2020, and number of job openings projected per year through 2020.

Here are the best 30 occupations that don’t trap you behind a desk. The figures for “Physical” and “Sitting” indicate how each occupation scores on overall physical activity and requirement of sitting, on a scale where 0 is minimal and 1 is maximal:

Use Common Sense with Assessments

I worked for 19 years at the nation’s premier testing company, and one thing I learned was not to be dogmatic about assessments. Even the makers of the mighty SAT exam freely admit that their scores do not predict college achievement as well as high school grades do. The SAT scores still have value, however, because when combined with high school grades, they give a better prediction than the grades could alone.

Something similar can be said about assessments that are designed to help you with career choice: Alone, they probably are not the best way to identify a promising career. But combined with other sources of information, they can be very helpful.

Incautious assessment users sometimes forget that psychological instruments are not as precise as a yardstick. Every assessment has a certain margin of error, meaning that although its scores put you into category x, there is a chance that you really belong in the neighboring category y. In baseball games, it’s usually pretty obvious whether a ball has landed in fair or foul territory. But imagine what accuracy would be possible if the ball were ten times as big as a beach ball and even more squishy: Even the instant replay would not resolve a borderline hit.

In baseball, it’s also helpful that the foul lines are at the edges of the area that the batter is aiming for. Now imagine what the game would be like if a line ran right down the middle of the field, and the score of the game depended on which side of the line the enormous beach ball fell on. For good measure, imagine that both right-handed and left-handed batters tended to hit the ball towards the middle. Now you have an idea why I’m reluctant to use the Myers-Briggs assessment. It attempts to place you on one side or the other of a bipolar range (e.g., introvert or extravert), although the normal distribution that is so typical of psychological characteristics clusters most people near the middle. There’s a very high likelihood that your actual location on this continuum is close enough to the middle that the inevitably imprecise measurement of the instrument will assign you to the wrong side of the middle.

Although I prefer to use assessments based on the Holland types, I have to caution that they also are unable to achieve a pinpoint focus. For the Holland types, let me change the metaphor from baseball to hopscotch, where a lot depends on which square your marker lands in. On the playgrounds where I grew up, the squares tended to be at least 10 inches across, but imagine how the game would be if they were only 3 inches across and your marker were a beanbag the size of a dinner plate. Fortunately, the Holland rationale is conceptually more forgiving of ambiguity than is the Myers-Briggs rationale, because it is not bipolar and accepts the notion that bordering types (for example, Realistic and Investigative) share some characteristics. If I can’t tell for certain whether my beanbag fell in the Realistic of Investigative square, I probably would not err greatly by favoring occupations coded RI, IR, or even just R or I.

But the really big mistake would be to rely solely on the assessment, whatever its rationale. Here are some other indicators of your interests and preferences that you should consider:
  • In what school subjects did I get the most enjoyment and the best grades?
  • What activities am I reluctant to drop at dinnertime?
  • What are my favorite sections of the newspaper or of news websites?
  • At a party, what kind of people would I be able to sustain a conversation with?
  • If you could meet the world’s greatest ____________ and get that person to share his or her secrets of success, what field would that person’s achievement be in? (Romance doesn’t count.)
Still another indicator is the opinion of a family member or of a friend who knows you very well. Explain the concepts that the assessment is designed to measure and ask this person which characteristics describe you best.

Making decisions is hard. People naturally tend to seek the quickest and easiest way to decide between x and y. This is one reason why people often perceive an assessment as the beginning and ending of the decision-making process. Instead, use an assessment as the start of a gradual process of self-discovery.
