Oh? I'd love to see something in policy that dictates anything of the sort.
After all, you have different pay levels for different markets. You people working side by side doing the same job with one guy making ten bucks an hour more than the other. What an asymmetrical distribution of money!!!!
When one has a serious problem that the other doesn't, absolutely. Only a fool would think otherwise.
It's an issue of how much it's going to cost to replace him, how long it's going to take to replace him, whether the new guy will be any good, how much potential the existing guy has, and so on. I may not like it or I may not care, but I won't disagree that it's a wise decision when it's obviously a wise decision.
