Wrongful dismissal is a legal term that refers to an employee being terminated from their job in violation of their employment contract or in breach of the law. This means that the reasons given for the dismissal were not valid, justifiable or legal, and as such, the employee may have grounds to take legal action against their former employer. In some cases, wrongful dismissal can also involve an employee being fired without proper notice or severance pay, which is in violation of labour laws.
