These jobs are also evergreen. They're in demand whether you have a booming economy or, well, this economy. And they are very steady and comparable to a small business type income without the risk of starting a small biz in this economy.
1. Air Traffic Controller
Can you believe that the average air traffic controller makes $159,000 per year? I know the work is portrayed as high stress in movies such as Pushing Tin. And it can be. You must be able to maintain focus have a good memory and make good decisions. You do have to go through very rigorous training. The FAA trains all ATC's in Oklahoma City. The training takes several months, but it can definitely be rewarding. Many of the ATC's hired in the mid '80s are retiring soon so there should be lots of entry level positions.
2. Nuclear Power Reactor Operator
Average salary is $128,000. And no, don't even think that if Homer Simpson can do it anybody can do it. This is another high skilled specialty job. You won't start out as a reactor operator. You'll have to work your way up. Once you have enough on the job training you can pursue a license through the Nuclear Regulatory Commission. Once you move into a senior operator position you'll be responsible for equipment that actually affects the operation of the reactor.
3. Director of Security (Physical, Personnel, Grounds, et al.)
As a director of security you could be responsible for the security of buildings, grounds or campuses, or even people. At $123,000 average salary this is a high salaried position. You need to be able to figure out the worst possible problems before they happen so you can be ready to avoid it, or take control when it happens. As a director you'll be responsible for training and managing a staff of professionals. There's lots of competition for these jobs and some can be physically dangerous. But we live in a dangerous world and there's sure to be demand for you in the future.
