IATSE Grey's AnatomyIATSE Local 80 has filed grievances against ABC Studios for the recent firing of several crew members on Grey’s Anatomy. The Local’s business manager Tom Davis filed the papers for the union. (UPDATE: Because of the nature of the complaints, Grey’s creator and executive producer Shonda Rhimes and her Shondaland production company were not filed against.) The long-term crew members were allegedly fired after speaking with Disney Human Resources about the “hostile work environment” they felt was created last season by director of photography Herbert Davis. A source tells Deadline that the grip crew, gaffer and both the A-camera and B-camera assistant cameramen were replaced. The parties are expected to meet on the matter sometime in the near future as a first step in the process. Charges of wrongful dismissal and firing in retaliation for a protected activity are being filed with both California and Federal labor departments against ABC Studios.
