NYC cultural workers who want to organize to protect their CIRS pension are covered by the National Labor Relations Act (NLRA)’s provisions regarding “protected concerted activity.” This section of the law gives union and nonunion workers alike the legal right to engage in a range of workplace activities, including the right to “engage in concerted activity for mutual aid and protection” and wear buttons, t-shirts, hats, and pins.

This one-page fact sheet from the U.S. Department of Labor summarizes these provisions of the NLRA: Employee Rights Poster.
