Twitter’s Janitors Are on Strike at Its San Francisco Headquarters

Janitors who clean Twitter’s headquarters in San Francisco are on strike ahead of their union contract ending.

Members of the SEIU Local 87, a custodians union in California, began their strike at 6 a.m. in San Francisco today, according to a statement from the California Labor Federation. The union says its contract with the social media company’s janitorial contractor ends on Dec. 9. Organizers claim Twitter’s new contractor has refused to rehire existing workers, which is required by San Francisco law.
