MLSA Executive Committee

The Executive Committee of the MLSA is responsible for the administration of the affairs of the MLSA and the development of the union. The committee consists of ten members elected by the membership for a two-year term, according to the rulebook of the Association. The Executive Committee meets 10-12 times a year. At the first meeting of each new Executive Committee after the AGM, the ten members elect the officers of the committee in a secret ballot. There are four officer roles: Chairperson, Deputy Chairperson, Treasurer and Honorary Secretary.
