JR1987:If an employer fires an employee for a
specific reason that they deem to be for
cause, and the accusation is not correct, and
it can be proven, can they be sued for
wrongful termination, defamation of
character, pain and suffering, etc?
You never defined what a "specific reason" was. If they felt that you were the slowest, tardiest, most absent, disinterested, useless employee on the payroll--and you weren't--they could term you. If they suspected you of embezzlement--they could term you. If they accused you of embezzlement, are informing everyone that you have embezzled, and no charges are being filed, they you may sue for damages.
Consult local counsel. (P.S.--You might not like the "Pay For" answers that you receive either.)
