You have a responsibility to not retaliate against employees for engaging in protected activity under the federal employment laws. In general, this means that you can’t take adverse actions, such as:
firing,
rejecting for a job or promotion,
giving lesser assignments,
forcing to take leave, or
otherwise negatively altering the terms and conditions of employment for an individual
because they complained about discrimination (whether the alleged discrimination was directed at them or another employee), or otherwise engaged in protected activity, or for taking an action that could dissuade a reasonable employee from raising a concern about a possible violation or engaging in other related protected activity because they complained about discrimination, whether the alleged discrimination was directed at them or another employee.
You may discipline or fire an employee if there is a non-retaliatory and non-discriminatory reason that would otherwise result in such consequences. However, you aren’t allowed to do anything in response to an activity that would discourage someone else from resisting or complaining about discrimination.
