Kelly Clarkson made her name singing songs like My Life Would Suck Without You and Because of You, but for the staff of her talk show The Kelly Clarkson Show, it sounds like their lives might suck because of conditions on her show. Staffers are leveling some pretty serious allegations about life behind-the-scenes of the popular talk show, according to Rolling Stone.

Speaking under the condition of anonymity, one current and 10 former employees spoke to the magazine complaining of being subjected to overwork, underpay and mental trauma in an overall toxic workplace.

As one former employee said, “NBC is protecting the show because it’s their new money maker, but Kelly has no clue how unhappy her staff is.” Another added, “I remember going up on the roof of the stage to cry, being like, ‘Oh, my gosh, what am I doing? Why am I putting myself through this?”

The former employees say the root of the problem is Duda, who hides from Clarkson what staffers say they’re enduring as part of the atmosphere Duda has created on set. One former employee said, “I think Alex Duda’s a monster. I have a friend who’s an executive producer who warned me about taking this job, because apparently she has done this on every show she’s worked on.”

The current and former employees did largely defend Kelly Clarkson herself. “Kelly is fantastic,” said one of the former employees. “I would be shocked if she knew. I’d be floored if she knew the staff wasn’t getting paid for two weeks of Christmas hiatus. The Kelly that I interacted with and that everyone knows would probably be pretty aghast to learn that.”

A representative for the show responded to the allegations, “We are committed to a safe and respectful work environment and take workplace complaints very seriously and to insinuate otherwise is untrue. When issues are reported they are promptly reviewed, investigated and acted upon as appropriate. The Kelly Clarkson Show strives to build a safe, respectful and equitable workplace that nurtures a culture of inclusivity and creativity.”
