One of the questions at the forefront of many employers’ minds when they are considering terminating an employee without cause is how much it is going to cost. Unless there is a written employment contract with an express termination clause, an employer’s obligation is to provide reasonable notice of termination. Since there is no set formula for determining the appropriate length of the reasonable notice period, employers (or their legal counsel) must estimate what they think the notice period could be, having regard to the employee’s age, length of service, character of employment, the availability of similar employment, and the employee’s skills and training. Often, employers and their legal counsel will use a rough rule of thumb of one month notice per year of service (although the courts have denied that such a rule of thumb exists).
