PSAC's decision-making process for electing leadership, setting bargaining priorities, setting and approving budgets, resolving internal disputes are set out in the PSAC Constitution and regulations. PSAC's activities and statements are also governed by policies. Both policies and the union's constitution and regulations are decided by delegates elected by their local or component to attend PSAC national convention.

By-laws and Regulations serve as the ‘constitution’ of the Agriculture Union, governing our structure and operations and ensuring democratic control by rank-and-file members.
