If your employment has been terminated, you may be entitled to damages for wrongful dismissal. Generally speaking, an employer can fire you without cause as long as you are given adequate notice or pay in lieu of notice.
The length of notice you are entitled to receive depends on whether or not you have a written contract that specifies the notice period. If there is no written contract, the length of notice you may be entitled to depends on many factors.
Some of the most important factors include your age, the duration of your service, your type of employment and level of compensation, as well as how difficult it will be for you to find suitable replacement employment.
