You may not be able to fight termination of employment if you were let go for a legitimate reason, such as restructuring or theft of company property. But if you believe you were terminated without just cause, there are some steps you can take. Make sure you understand why you're being terminated. If you can, appeal the decision with your employer or the company's human resources department. Request copies of documents, including your employment contract, any communications between you and your employer regarding your performance, as well as your employment file. If you have a union, contact your representative. You can also consult an employment lawyer to take your case to court if you have a case.
