Companies can do several things to avoid retaliation claims. First, companies should have a written policy that prohibits retaliation. Second, supervisors should not make firing decisions when they are angry. Third, companies should offer supervisors training about the subject and how to react when they receive a complaint from an employee. Fourth, supervisors should apply policies and practices consistently. Fifth, companies should publish their complaint reporting procedures. Finally, companies should follow up after an employee has complained to ensure there has been no retaliation.
