Although Florida employers have no obligation to give a reason or cause for terminating their “at will” employees, their failure to give a reason at the time of termination may increase litigation costs. In Mock v. Bell Helicopter Textron, Inc., the Eleventh Circuit held that the employer’s refusal to give the employee a reason on the day of his firing was enough to preclude dismissal and require a jury trial. The court reasoned that a jury could reasonably find that the employer’s evidence of unsatisfactory job performance (including a post-termination letter stating that reason) was not the real reason for the discharge based on the employer’s refusal to give that reason at the time.
