Who We Are

Our union started at Sierra Club in 1992 as the John Muir Local 100, a small union limited to some staff at Sierra Club, and was refounded as the Progressive Workers Union in 2017. Currently, PWU represents over 550 nonprofit workers across some of the largest and most influential organizations in the country, and our members and leaders work every day fighting for environmental, economic, and racial justice within the climate movement.
