Alberta Union of Provincial Employees represents a large number of government and board employees throughout the province. For administrative purposes, AUPE designates each department or unit a local number. The Alberta Union of Provincial Employees, Local 52 is the sole bargaining agent for The University of Calgary support staff and was formed by an enactment of the Alberta legislature on June 14, 1976. Previously, The University of Calgary's support staff were served by the Civil Service Association of Alberta. Local 52 is autonomous within the structure of AUPE and bargains independently within AUPE's constitution. The Local consists of over 2000 salaried and casual members and is administered by four chapters which each elect an executive to look after the chapter's interest. Local 52's chapters are Operational/Administrative, General, Specialist/Advisor, and Trades/Technical. These chapters reflect the job families staff are classified under. Representatives to Local 52 Council are elected by the chapters, and the Local executive is elected from among the members of the Council.
