Hollywood members of the International Brotherhood of Teamsters have voted to strike the TV commercials industry when their contract expires on Jan. 31 — if the producers do not sweeten their offer.

Members of Teamsters Local 399, which covers 14 Western States, voted 414-36 on Sunday to reject the “last, best, final” offer on a new two-year contract from the Association of Independent Commercial Producers.

“Per the International Brotherhood of Teamsters Constitution, a no vote authorizes a strike,” the local said on its website. “We have notified the AICP and are awaiting their response.”

Negotiators for the AICP and the Teamsters reached a tentative deal Dec. 9 for a successor contract.

Matt Miller, president and CEO of the AICP, told Variety that he was disappointed by the member vote and has reached out to the union to discuss it.

“The deal will have a positive employment impact,” Miller added. “We’re not taking the vote lightly.”

Steve Dayan, secretary-treasurer of Local 399, told Variety that members opposed the tentative deal due to its provisions expanding low-budget shoots. Based on the Directors Guild of America’s contract, the  maximum daily spend to qualify as low-budget would have been increased to $125,000 from $75,000 a day.

California, unlike many other states, does not offer incentives for commercial productions.

Dayan also said he had reached out to the AICP following the “no” vote.
