About Us


We are nearly 50,000 private security officers united in SEIU, the nation’s largest security officers union. We protect property and people in facilities–including high-rise commercial buildings, banks, power plants, airports, warehouses, stadiums and the high-tech industry–all across America.

Our goal is to raise our industry’s standards by increasing professionalism and training, improving wages and benefits, and developing career opportunities for security officers.

Through our national, community-based campaign, Stand for Security, we have reached out to fellow security officers, building owners, security providers, spiritual leaders, and elected officials across the country in order to bring good jobs to our communities and more safety and protection to those we serve.

We recognize that today’s world is shrinking–many security employers are global enterprises–and so we have begun to work with security officers in other countries to raise industry standards across the globe.
