About Us

SEIU Colorado is connecting people from every corner of Colorado to put the power back in the hands of working people and their communities, who will take bold action to ensure that the economy works for all of us, not just the wealthy few. Centered around the value that working people keep our state running, fighting to ensure that all jobs are family sustaining jobs with protections against discrimination and bad bosses. We uplift the leadership and voices of those who are directly impacted by decisions made at the capitol and those  historically left behind.

SEIU Local 105

SEIU 105 is one of the fastest-growing unions in Colorado, uniting over 8,000 healthcare, janitorial, security, and airport workers throughout the state and the southwest.

Founded in 1939, SEIU Local 105 is united by the belief in the dignity and worth of workers and the services they provide and dedicated to improving the lives of workers and their families and creating a more just and humane society.

Colorado WINS

Colorado Workers for Innovative and New Solutions (WINS) is a union representing more than 24,000 state employees who work to ensure our quality of life in communities in every corner of our state.

In 2020, state employees came together through to pass a game changing bill that allows state workers to negotiate with their employer, the State of Colorado, for better wages, benefits, and working conditions.

Colorado Care Workers Unite

Colorado Care Workers Unite was founded in 2018 to bring caregivers to the forefront in decisions that affect workers, their families and their clients. Care workers do essential, compassionate work but the system doesn’t work for anyone. 

Colorado Care Workers Unite is creating an opportunity for workers to stand together for better pay, rights on the job and to provide a well-trained workforce that meets the needs of our growing aging population.







From our healthcare facilities and airports to our highways and even people’s homes, we keep essential businesses running and our communities safe, clean, healthy, and cared for.

As Coloradans, we know what’s possible when we stand together. Whether we live in Denver or Durango, Fort Morgan or Fort Collins, Black, white, or brown, we all want the same things: to make a decent living, see our loved ones of all ages lead full, healthy lives, and to live in a thriving community. By joining together, we decide the future—a future where every Coloradan, no matter our race, zip code or background, can thrive.
