The staff of SEIU Local 99 work hand-in-hand with members to build a strong union by assisting and supporting members in building a lasting, member-led leadership structure directly in their workplaces.

Some of this work entails the day-to-day affairs at the union office, field organizing, facilitating meetings, representing members, keeping members informed, managing our union’s finances, and all the activities done on behalf and in the interest of the membership at-large.
