Actually, your employer is not required to pay for unused sick time or vacation time when your employment terminates, unless and only if there was a policy in place at the employer that they pay for these things. So if there was such a policy, they'd have to follow-it; but if there was no policy to pay out unused vacation or sick leave, they don't need to pay it at all--or alternately, could use it the way they are.As to bonus pay, if there was a policy that you'd be paid it even if your employment terminates, they have to pay you as per that policy. But it would be legal to not pay on termination, so if there was no policy in place guarantying you this money, they again could do what they have.
