There are two tiers of union leadership within SIASU
The Branch Committee
The Executive Council
At the branch level, unionised employees of the branch elect branch delegates. The branch delegates will form their own committees to serve members at branch, or company, level.
The branch committees will :
Try to resolve grievances through negotiations with management.
Serve as links between workers and leaders at union headquarters
At Union's headquarter level, branch delegates are elected through a Convention of Delegates to serve in the Union Executive Council which is responsible for the effective operation of the union. The Executive Council elects among themselves General-Secretary, the President, the Vice-Presidents, the Treasurer and other principal officials. The Executive Council also appoints committees to deal with specific areas such as industrial relations, labour and education, social and welfare services, culture and sports, occupational health and safety, women's committee and administration and publicity.
The Constitution of SIASU describes in greater details the specific duties and roles of the principal officials and the delegates.
