SAG-AFTRA has ordered its members not to work on the cable TV series “Knife Fight,” asserting that producer Authentic Entertainment has refused to sign a collective bargaining agreement.

SAG-AFTRA issued a “no-contract, no-work” order for the underground cooking competition hosted by Ilan Hall, which airs on the Esquire Network.

“No member may accept work or appear as a guest on this series,” the order said. “Violating this order may result in disciplinary action in accordance with the SAG-AFTRA Constitution.”

The union’s David Besbris added, “There are guest judges that change from episode to episodes as well as a host. Our no-work order applies to both.”

Authentic Entertainment did not respond to a request for comment.
