This article examines a statutory expedited grievance arbitration procedure adopted in Ontario, Canada, in 1979. The primary objective is to consider the effectiveness of the expedited procedure, which includes mediation, as an alternative dispute resolution technique. After reviewing some of the problems of cost and time delays, the characteristics of the statutory procedure are described. An exami-nation of the experience with expedited arbitration is also included. The analysis will consider how extensively expedited procedures are used (including whether expedited arbitration is preferred for certain types of disputes, for example, discharge grievances), the effect of grievance mediation on dispute resolution, and the savings in time and cost provided by expedited arbitration procedures.
