History
Explore key moments in the history of SEIU.
1921: Workers Form the Building Service Employees Union
When the Building Service Employees Union (BSEIU) first formed in Chicago in 1921, it was far ahead of its time. Unlike most unions of its day, BSEIU was integrated. In fact, Black, immigrant and women members already held leadership roles. As William Quesse, the union’s first president and son of German immigrants said, “we are composed of all creeds, colors and nationalities, and do not allow anyone to use prejudice in the organization against each other.”
1934: New York Building Workers Strike & Win Their Union
Building service workers formed 32-B in April of 1934 and went on strike in November. Manhattan’s skyscrapers were largely inaccessible without elevator operators, but even by the standards of the Great Depression, building service workers’ wages were low and they were treated poorly. Building workers in around 400 buildings in midtown Manhattan’s garment district went on strike and won union rights.
1941: Healthcare Workers Join BSEIU and Win Ground-Breaking Contract
Inspired by the 1934 general strike in San Francisco, healthcare workers organized their hospital. They then joined BSEIU and won a groundbreaking first contract with the San Francisco Hospital Conference, covering 11 hospitals. This laid the groundwork for present-day SEIU to eventually become the country’s largest healthcare union.
1953: Public Workers Join BSEIU
Elinor Marshall Glenn, the first woman to become General Manager at SEIU Local 434, helped organize thousands of public hospital workers in LA County.

BSEIU President David Sullivan established a Civil Rights Committee and created an action plan to support the fight against segregation and racism. In 1963 President Sullivan, and many other BSEIU members, attended the March on Washington.
1968: BSEIU Officially Becomes SEIU
1975: Working Women’s Movement 9 to 5 Joins with SEIU
In 1972, women office workers banded together to form 9to5, National Association of Working Women. After three years, their founders realized they needed a way to hold their bosses accountable. They joined SEIU and formed Local 925 in Boston. The movement inspired the box office success comedy, 9 to 5, starring Dolly Parton, Lily Tomlin and Jane Fonda.
1980’s: Home Care Workers Win Their Union
SEIU began organizing home care workers in the early 1980s. SEIU currently represents over 740,000 home care workers across the country, including over 100,000 in CA alone.
1984: As Healthcare Members Fight HIV/AIDS Crisis, Union Advocates for LGBT Members
Considered radical at the time, as SEIU healthcare members cared for HIV/AIDS patients, the union worked to raise awareness and spread information about the need for compassionate care. SEIU also advocated for its LGBT members, adopting a resolution supporting benefits for LGBT members and their families. The documentary, 5B features SEIU member Mary Magee.
1990: Janitors Rise Up for Justice
In the 1980s, janitor wages stagnated and workers were losing their benefits. Janitors working in Los Angeles began to organize. On June 15, 1990, members of the janitor’s union in Los Angeles launched a strike & peaceful protest to win much needed workplace improvements. The janitors—predominantly underpaid immigrant women & men—were up against a powerful business community & multinational corporations. On that day, janitors, their families and supporters marched through the high-rise buildings of Century City, where they were met with aggressive force at the hands of the Los Angeles Police Department. News cameras captured baton-wielding police officers striking custodians—including men and women lying face-down on the ground. Janitors were injured. Some very badly. More than 60 would end up in hospital rooms. Two of the hospitalized were pregnant women - one who would miscarry. This event sparked the Justice for Janitors movement that spread across the country. Since the movement began in 1990, more than 160,000 janitors have won their union and their determination inspired the film Bread and Roses.
