You have notice periods ! You can not be fired on the spot with no payment !
Should the employer fail to fulfill the said request the employee is entitled to another interview with the employer in the presence of his or her union representative or other representative of the union, should he or she request so.
Notice periods range from 12 days to six months (three months are common), depending on rules of the applicable collective agreement.
An employment which has been terminated by either party remains intact until the end of the notice period, which means that rights and obligations under the agreement remain unchanged during the period. The parties can however come to an agreement to end their relationship before the notice period expires.
