In July 2019, Baldwin signed a letter to United States Secretary of Labor Alexander Acosta that advocated that the U.S. Occupational Safety and Health Administration (OSHA) make a full investigation into a complaint filed on May 20 by a group of Chicago-area employees of McDonald's that detailed instances of workplace violence, such as customers throwing hot coffee and threatening employees with firearms. The senators argued that McDonald's could and should "do more to protect its employees, but employers will not take seriously their obligations to provide a safe workplace if OSHA does not enforce workers rights to a hazard-free workplace."
