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.

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.

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 Fights for Civil Rights

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.

BSEIU Officially Becomes SEIU

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.

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.

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.

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.

SEIU reaches one million members.

Airport Workers in Los Angeles Unite, Leading to Nationwide Campaign

Airport workers, including baggage handlers, wheelchair attendants and cabin cleaners, first united and won their union at Los Angeles International Airport. Contracted airport workers, who are primarily immigrants and people of color, joined together across differences to confront corporate power and have since won higher wages and other benefits for more than 155,000 airport workers at 23 airports across the country. They continue to be part of the fight for $15 and a union.

First Security Officers Win Their Union with SEIU

Security officers united across the industry — from hospitals, schools, parks, transportation hubs, businesses, libraries and government institutions — to raise work standards. Today, SEIU is the nation’s largest Security Officers union, with 70,000 union officers in cities like Philadelphia, New York City, Washington DC, Chicago, Columbus, Denver, Minneapolis, Seattle, Silicon Valley, San Francisco, Los Angeles, Houston and more.

Childcare Workers Win a Union & Launch a National Campaign

After a decade of organizing for the right to collectively bargain, 49,000 family child care providers in Illinois win their union election and begin bargaining a ground-breaking contract that will increase their pay by as much as 35%, provide access to health care for the first time, and improve the quality of care for the children they serve.  This ushers in a wave of child care organizing across the country, improving the lives of tens of thousands more child care workers and bringing them into the movement for a better child care system for all working families.

First Woman Elected to Lead SEIU

In 2010, Mary Kay Henry became the first woman elected to the office of International President of SEIU). Under her leadership, SEIU members have won major victories to improve the jobs of healthcare, property services and public sector workers across the United States, Canada and Puerto Rico. Henry’s decision to back the courageous fast-food workers and other service and care workers in the historic "Fight for $15 and a Union" movement has helped 24 million working Americans win wage increases.

Fast Food Workers Help Ignite Low-Wage Worker Movement

200 fast-food workers went on strike in New York, helping to ignite a conversation on low wages, inequality, race and corporate power in America. Soon thereafter, the movement adopted the name “Fight for $15 and a Union.” Their movement has pushed more than two dozen cities and counties and more than half a dozen states to move toward a $15 minimum wage and many more to increase wages. The group continues to demand accountability for low wages and poor working conditions from employers throughout the industry, most notably McDonalds.

Higher Education Workers Begin to Organize

Despite years of education and doing much of the same work as their tenured counterparts, adjunct professors in Boston, as the rest of the country, faced precarious working conditions, no benefits and low pay. They began to organize their unions at schools across the city. The movement spread across the country, to graduate workers, non-tenure track and professional staff, with workers at more than 70 campuses nationwide winning their union and improving working conditions.
