Workers at Casa Bonita voted to unionize with Actors’ Equity Association (Equity) and Theatrical Stage Employees (IATSE) Local 7. The workers, about 80 cliff divers, magicians, actors, puppeteers and others at the Lakeland, Colorado, Mexican eatery, are seeking to address pay and other concerns, such as insufficient training, scheduling and safety from “abusive patrons emboldened by alcohol.” The restaurant was recently bought by “South Park” creators Trey Parker and Matt Stone.
