A lot to digest. The two that didn't are my best employees. My business would crumble if one left. She may be the best CMA ever. She would never cheat me. I can't put anything on them.
I don't understand the other two. I could understand personal and sick time. Those are few and hard to keep track of. So, if you took three sick days over four months, and the pay stub said you have two left. But vacation time is altogether different.
Not sure if they have a labor board complaint. Maine is an as is state, and you can fire someone for any reason. I suppose you wouldn't want to name it. I am definitely not a lawyer.
Personally, I think the problem goes back to the employee manual. It should state that any amounts stated on your voided pay check are for guidance only, and you are responsible for your own time.
It was caught by my practice consultant who is like a physician to a nurse compared to an office manager. She noticed employees putting in for time when they had just taken vacation, and she keeps track of EVERYTHING.
