Regarding accrued vacation time - when a firm offers "unlimited" vacation, that means they no longer have that on their books as a liability (since the employees aren't building up a balance). So you don't get it paid to you when you leave. If your firm converts to unlimited vacation and you have a balance at the time, talk to them about being paid for it. Either lump-sum right then, or offer to let them pay it to you over time. You earned it, you deserve to either take the time or get the money.
