The MGEU is a democratically-run organization.

Through "majority rule," members elect their fellow members as stewards, table officers and convention delegates. At the MGEU Convention held every two years, a member-based board of directors works with elected delegates to make decisions regarding overall union policy, direction and goals.

Throughout the year, the Provincial Officers provide direction for the union along with the rest of the Board of Directors,who are elected from specific Locals and each provincial Area. As well, Standing Committees, chaired by a board member plus one member elected from each provincial Area, work throughout the year to forward progressive policies and benefits on behalf of their fellow members.
