Not following you. How do relocation expenses come into it?
(Exempt vs. non-exempt does not matter in this case.)
It is almost certainly not legal (though I would like to hear more about the relocation expenses) but the problem is that GA is one state that has no laws on the release of final paychecks and does not accept wage claims. You would be referred to the US DOL, which only will fight for the minimum owed by law.
