In some cases, the firing of an employee is a discriminatory act. Although an employer may often claim the dismissal was for "just cause", these discriminatory acts are often because of the employee's legally protected characteristics, which vary from place to place. They may include physical or mental disability, age, race, religion, gender, HIV status or sexual orientation. Other unjust firings may result from a workplace manager or supervisor wanting to retaliate against an employee. Often, this is because the worker reported wrongdoing (often, but not always sexual harassment or other misconduct) on the part of the supervisor. Such terminations are often illegal. Many successful lawsuits have resulted from discriminatory or retaliatory termination.
