Hollywood unions have reached an agreement with the major studios on protocols to allow the industry to safely restart production amid the ongoing COVID-19 pandemic. The agreement was announced yesterday. The announcement marked a three and a half month negotiation period after the unions issued their “Safe Way Forward” guidelines on June 12 following a June 1 “white paper” by the Industry-Wide Labor-Management Safety Committee Task Forces comprised of the unions and studios.
