Get Involved

If you’ve been wanting to get political, but haven’t known where to start – or even if you’re old hat at political activism and are looking for a new challenge, we’ve got just the thing for you.

Callout Activism

Callouts, organized by CAST’s Community Action Planning (CAP) Committee, are intended to: maintain CAST’s visibility and inspire local people to engage as activists; educate the public about critical political events and policy decisions, and encourage effective responses; inform people about upcoming social justice action opportunities; and engage new activists to build community.

Live Callouts are held the first Thursday evening of each month during the Spring, Summer, and Fall in Central Square, Cambridge. By passing out flyers, holding signs, and engaging in conversations with passersby, participants can end those Thursdays in a meaningful, connecting, and energizing way. Stand Up, Speak Out!

Virtual Callout flyers are posted in CAST’s e-newsletter, The Weekly ForCAST. As with the flyers distributed at live Callouts, the Virtual Callout flyers provide information about and encourage action on critical current issues related to CAST’s mission and goals.


CAST works on elections throughout the year, as they come up. We typically hold phonebanks and Postcards to Voters for candidates both local and further afield, including Annie Kuster in New Hampshire, Doug Jones in Alabama and Jon Ossoff in Georgia’s Sixth District. We also run canvassing trips to New Hampshire or elsewhere, as needed. We provide training for all of our election activities.

Peacekeeping is essential to ensuring that public events – including rallies/demonstrations, marches, civil disobedience, and other actions – are nonviolent. Peacekeepers set and maintain a tone of cooperation and communication. There are four primary roles of a peacekeeper:

  • Facilitate
  • Communicate
  • Coordinate
  • De-escalate

CAST members collectively possess decades of experience in peacekeeping. If you are interested in learning more about this vital aspect of nonviolent activism and/or would like to train to be a peacekeeper, please contact
