The West Coast members of the Intl. Alliance of Theatrical Employees — Hollywood’s key below-the-line union — have reached a tentative agreement with producers on a three-year successor deal to the master contract.

The new deal was concluded Sunday after two weeks of negotiations between the union and the Alliance of Motion Picture and Television Producers. The deal is along the same lines as the agreements negotiated by SAG-AFTRA, the Directors Guild of America and the Writers Guild of America with a 3% annual wage hike and 0.5% increase in contributions to the pension and health fund, according to sources close to the talks.

The IATSE and the AMPTP had no comment. If ratified by members, the new deal goes into effect on July 31, when the current deal expires.

The deal covers the 14 Hollywood-based locals representing over 38,000 members of the IATSE working in motion picture and TV.

The AMPTP will begin a week of negotiations on May 18 with Hollywood Teamster drivers along with four other basic craft unions for a successor deal to their current three-year contract, which also expires July 31.
