One employee said that working on the popular late-night show had turned from a dream to a nightmare for many staffers.

NBC also issued a statement.

“We are incredibly proud of The Tonight Show, and providing a respectful working environment is a top priority,” it said. “As in any workplace, we have had employees raise issues, those have been investigated and action has been taken where appropriate.”

Rolling Stone, however, had reported that staff complaints had fallen on deaf ears.
