When I accepted the job I currently have I knew exactly what my compensation and benefits would be. When I have had reviews I negotiate with my boss for my raise based on the structure that was set up by the owner of the company. If I don't like the raise I get then I can either A. Accept the raise that I was given. Or... B. Go seek another opportunity somewhere else. It is really that simple. That logic is the same if you make 30k per year, 100k per year, or 4 million per year. We live in a free market... we have the power to seek out any opportunities that we choose.
Tom Brady seems like a pretty smart guy... He chose to play football and he gets paid quite well to do so. I am sure he could have chosen to work in the business world instead but he would most likely be taking a huge pay cut. He chose to play football and in signing his contract he understood the compensation and benefits he would receive for doing so. He is under contract. If he decides he no longer likes his compensation or benefits then he can go find something else to do outside of football. Simple. You and I both know these guys aren't just going to walk away from the game though... What else are they going to do that will pay them nearly as much? No... instead they will try to tell their boss exactly how their pay structure should be, how their benefits should be, what their raises should be, how much work they should have to do, how much training they should have to do, what their job responsibilities will be, how their job performance should be judged, etc.... This isn't about their work, this isn't about being fair, this isn't about their job performance, etc... this is about the employee trying to tell the boss how things are going to be due to their inflated sense of entitlement. In this NFL dreamworld they live in that might work but in the real world their plan is an EPIC FAIL.
