I'm not so sure that getting another job isn't a solution. At some point you have to ask yourself if what you're doing (as a job) and where you're working is worth it. I spent the 90s and early 2000s working in a high stress, fast paced, but very lucrative job. Lots of travel and 60-70 work weeks were common. Eventually I decided I was done with that and took a less stressful, but lower paying job."This problem" <- refers to the problem highlighted in the article. Not the irrelevant "being shot at" problem which has no bearing on the jobs this article is about. Okay, so "the military/police" is an answer to my challenge, but it's a hollow, impractical one. The "if they don't like what they do they can quit" is neither practical nor a solution, and improving these corporate jobs isn't mutually exclusive from improving the lives or safety of people this study isn't about.
At the end of the day, you have to decide if what you're doing is worth the paycheck. You simply can't just say, pay me more but I'll do less. That's why I liked the jobs I had that had bonuses or commissions tied to my personal performance. The more I sold or helped sell, the more I got paid.
