Lets say that you are a high performance, high-value employee. Your contract has recently ended, but your employee places great value on your remaining with the firm, and to keep you, they pay you a substantial bonus. Three months before your contract is up again, however, you are badly injured. You are badly injured because your employer has put you in a dangerous, high-risk situation that leaves you vulnerable to such injury--in fact, a number of your comrades suffer such injuries nearly every day, and some die as a result.
As a result of your injuries, you're disabled, and have to leave your employer. But, you didn't fulfill the complete term of your contract, and now your employer wants some of that bonus money back. What kind of heartless entity would do that. The United States Department of Defense, of course. Just ask Jason Fox. That's some down home compassionate conservatism.
