FMLA and Workers' Compensation
"The Act provides that a serious health condition may result from injury to the employee on or off the job. If the employer designates the leave as FMLA leave in accordance with § 825.300(d), the leave counts against the employee's FMLA leave entitlement. Because the workers' compensation absence is not unpaid, the provision for substitution of the employee's accrued paid leave is not applicable, and neither the employee nor the employer may require the substitution of paid leave. However, employers and employees may agree, where state law permits, to have paid leave supplement workers' compensation benefits, such as in the case where workers' compensation only provides replacement income for two thirds of an employee's salary. If the health care provider treating the employee for the workers' compensation injury certifies the employee is able to return to a light duty job but is unable to return to the same or equivalent job, the employee may decline the employer's offer of a light duty job. As a result the employee may lose workers' compensation payments, but is entitled to remain on unpaid FMLA leave until the employee's FMLA leave entitlement is exhausted. As of the date workers' compensation benefits cease, the substitution provision becomes applicable and either the employee may elect or the employer may require the use of accrued paid leave.” 29 C.F.R. §825.207(e). See also, 29 C.F.R. §§ 825.210(f), 825.216(d), 825.220(d), 825.307(a) and 825.702(d)(1) and (2) regarding the relationship between workers' compensation absences and FMLA leave.
