At over 23,000 members and growing, SEIU 509 is the union for Massachusetts health and human service workers and educators.
Generation after generation, Native American workers have shown us how to organize, resist, and win.

This month, we honor that legacy and stand firm against attacks on equity and representation. The fight continues and our solidarity is unwavering!
