Fox’s WNYW is the perpetual ratings champ with its 10 p.m. newscasts. But even Rupert Murdoch 21st Century Fox isn’t immune to belt-tightening.

Tuned In has learned that WNYW has laid off several behind-the-scenes staffers. We’re told that a “bunch” of engineers and videographers were bounced, cre4ating an uneasy feeling at the East 67th Street broadcast complex.

Once again, we were refused a comment by a Fox spokesperson.

“This wasn’t unexpected, but there were hopes [that] a last minute deal would be worked out to save some positions,” an insider says. “Unfortunately, that didn’t happen.”

Earlier this month, Fox dramatically severed ties with local news at Secaucus-based WWOR, causing the company to get roundly criticized by many, including elected officials.

Whether Fox will pay anchor WWOR anchor Harry Martin to remain with the company as a Channel 5 reporter is still unclear.
