I certainly do not have a handle on baseball's anti-trust exemption or labor rules in this. Spring training pay might at least be a concession, in the end. Do you send your employees for training, and do you pay them for it? I'm sure there's a night and day difference between whatever business you are in (you don't have to say,) and Major League Baseball. But the argument I hear you making is essentially that if an employee doesn't like the fact that their employer won't pay them for annual training in their profession, he she can quit and go do something else. I could be wrong, but that doesn't sound like the law, to not pay for job training.
