Probation (a) The Employer may reject a probationary employee for just cause. The Employer will provide the reasons for the rejection in writing. A rejection during probation will not be considered a dismissal for the purpose of Clause 11.2 (Dismissal and Suspension) of this agreement. The test of just cause for rejection will be a test of suitability of the probationary employee for continued employment in the position to which they have been appointed, provided that the factors involved in suitability could reasonably be expected to affect work performance. (b) The probationary period for supervisory employees and professional employees (registrants of a regulatory body) will be six months worked or the equivalent number of hours worked as based on the normal hours of work of a full-time employee, whichever occurs last. Notwithstanding the foregoing, the probationary period will not exceed nine calendar months. (c) The probationary period for all other employees will be three months worked or the equivalent number of hours worked as based on the normal hours of work of a full-time employee, whichever occurs last. Notwithstanding the foregoing, the probationary period will not exceed six calendar months. (d) The Employer, with the agreement of the Union, may extend the probationary period for a further period not to exceed three months. Following discussion with the Union, the Union will not unreasonably deny the extension. (e) Where an employee feels they have been aggrieved by the decision of the Employer to reject the employee during the probationary period, they may grieve the decision pursuant to the grievance procedure outlined in Article 9 (Grievances) of this agreement commencing at Step 3.
