The collective agreement is the basic corner-stone of collective bargaining in North America. From its beginning the problem of making the provisions of collective agreements binding on the parties who entered into them has been a major concern of unions, employers, employees and increasingly of public authorities. This volume, one of the Centre’s Research Series, traces in depth the historical development of procedures in Canada for the enforcement of collective agreement provisions. The main emphasis is upon those methods developed by Canadian legislatures to provide orderly means of enforcement and thus contribute to a greater stability of union-management relations.
