Canada Post Corp v Canadian Union of Postal Workers

Extra Hours, Casual Employees, Regular Employees, Constructive High Mail Volume, Replacement Casuals


The Union, representing thirty-nine Grievors, alleges that on each shift in respect of which a grievance was filed, high mail volume necessitated the working of extra hours and the Employer used casual employees without first offering the extra work to regular employees, contrary to the Collective Agreement. Replacement casuals were assigned to the Halifax postal station, mostly during the evening shift. The casuals were sufficiently and firmly ensconced that management would post weekly work schedules showing rotation days off, as for regular employees. The Union argued that the employment of such casuals meant "constructive" high mail volume which therefore should be extra work for regular employees.
