I'll be a little more blunt here than I was on the other board. (I quite realize that you haven't had a chance to see my other answer yet.)

Neither Federal nor state law (in any state) cares one hoot IF you get vacation, let alone when it resets. A small handful of states, not including yours, require that anything unused be paid out on termination, and one state (not yours) requires that it accrue as you go instead of getting it as a block. NO state has any laws that require it to reset in any particular way. There is nothing at all illegal about this policy, sorry.

There's no need for an employer to "trick" you out of any time since they have no legal obligation to offer it in the first place.
