Perhaps not, according to the First Circuit Court of Appeals. Not all retaliation is the same, the court reminds us in its December 14, 2016 decision in Chase v. U.S. Postal Service. Evidence that a supervisor retaliated because of an employee’s workers’ compensation claim does not itself prove the supervisor also retaliated because the employee took concurrent leave under the Family and Medical Leave Act (FMLA). Mocking an employee’s allegedly fake injury does not necessarily show hostility toward use of FMLA leave.
