Organize. Build Power. Win Justice.

About Us

The Pioneer Valley Workers’ Center builds power with low-wage and immigrant workers throughout Western Massachusetts. Together, we organize to build community and win real change in the lives of working people.

We envision a society free of exploitation and oppression, where all people have the resources to live happy lives.

As we fight to dismantle the old society, we wish to build institutions that directly represent the interests of working people and create an economy that is rooted in democracy and ecological sustainability. In the past, workers have built workers councils and cooperatives to democratically make decisions about their workplaces. This vision and the beliefs it is built on are woven throughout all of our projects and campaigns.

The PVWC is committed to taking a range of actions to address issues of concern.

Engage in innovative and creative worker-driven organizing to address issues of concern to working, low-wage and immigrant workers in the Pioneer Valley

Leadership Development
Create avenues for leadership development and organizing skills so that workers can advocate for themselves and others while building a participatory democratic space for the promotion and defense of worker rights

Coalition Building
Build coalitions and partnerships with unions, community groups, faith groups, and individuals .to increase organizing opportunities

Political Power
Expand our political power in the Pioneer Valley and strengthen the voice of vulnerable workers in the political process
