SEIU Local 503, also known as the Oregon Public Employees Union (OPEU), is a member-driven organization representing over 72,000 workers across Oregon. Members include state, local government, university, and non-profit employees, as well as homecare workers, personal support workers, and nursing home workers. The union advocates for fair wages, quality benefits, secure retirements, and safe working conditions through collective bargaining, political action, and community engagement. SEIU Local 503 is committed to improving the lives of working families and strengthening public services for all Oregonians.
Serves as the main administrative center for union operations, strategic planning, statewide campaign coordination, member services, and legislative advocacy.
Standard office facilities equipped for union operations, including meeting rooms for member gatherings and negotiations, staff offices, and communication infrastructure. Designed to be accessible to members.
A mission-driven and advocacy-focused environment, emphasizing collective action, member empowerment, and social justice. Staff often work collaboratively on campaigns, negotiations, and member support.
The Salem headquarters is strategically located in Oregon's state capital, facilitating direct engagement with state government and legislative processes vital to the union's advocacy for public employees and services.
SEIU Local 503's operations and membership are primarily concentrated within the state of Oregon, USA. As a local chapter of the Service Employees International Union (SEIU), it is part of a larger international organization that has members in the US, Canada, and Puerto Rico.
