§ 825.219 Rights of a key employee.
(a) An employer who believes that reinstatement may be denied to a key employee, must give written notice to the employee at the time the employee gives notice of the need for FMLA leave (or when FMLA leave commences, if earlier) that he or she qualifies as a key employee. At the same time, the employer must also fully inform the employee of the potential consequences with respect to reinstatement and maintenance of health benefits if the employer should determine that substantial and grievous economic injury to the employer's operations will result if the employee is reinstated from FMLA leave. If such notice cannot be given immediately because of the need to determine whether the employee is a key employee, it shall be given as soon as practicable after being notified of a need for leave (or the commencement of leave, if earlier). It is expected that in most circumstances there will be no desire that an employee be denied restoration after FMLA leave and, therefore, there would be no need to provide such notice. However, an employer who fails to provide such timely notice will lose its right to deny restoration even if substantial and grievous economic injury will result from reinstatement.
