Termination of employment is a serious matter. It can be an upsetting and emotional time for employees, who will naturally have questions about why they were asked to leave.
While your employer is not required to give a reason for termination, they are encouraged to do so to help you better understand the situation and achieve closure. If your employer did not state the reason in your termination letter, you can talk to the company's management or Human Resources department to find out the reason.
If you feel you have been unfairly terminated, you can file a wrongful dismissal claim with TADM.
