I have a 403B account that would become fully vested in March. I also have an opportunity to take a new job. If I gave notice before the vestment, but continued working through the vestment date, would I definitely get vested or could they refuse if I give notice?
They could let you go immediately, and you would not be vested. Even though you're trying to do the right thing by giving notice, it's safer to stay silent until you're vested, then quit.
