The sound of construction work halting at UPS' Plainfield hub: 'We rise together, homie!' - Indy Star Antoine Dangerfield didn't set out to become a labor leader The work stoppage centered around two contractors: Material Handling Systems Inc., a Louisville-area contractor that is building the UPS hub, and Contractors Resource Inc., a Texas staffing firm, which Dangerfield said employed him and his co-workers. The last straw, Dangerfield said, was when the manager in question became angry and forced some Hispanic workers to leave after no one agreed to translate for him during a safety meeting. Dangerfield said the manager had a reputation for treating white workers well, but was "hard on everybody else." MHS in a statement called the dispute that led to the walk off a matter of "confusion."
