Employees of Jimmy Fallon’s late-night show, “The Tonight Show Starring Jimmy Fallon,” have alleged that the workplace is toxic and has led to some of them having suicidal thoughts.

One unnamed employee described an incident in 2017 where Fallon crossed out jokes on a piece of paper he was holding, then appeared confused. The employee said that Fallon seemed drunk and didn’t know what he was doing.

Other employees alleged that Fallon snaps at and belittles crew members and employees, and expresses irritation over minor things. They said that the atmosphere of stress and fear caused them to go on anti-anxiety medication, one person lost 20 pounds, four employees say they are in therapy because of their experiences, and three said they had suicidal thoughts.

Fallon has previously denied drinking, but employees allege seeing him seemingly inebriated at work, and smelling alcohol on his breath during the workday. They also alleged that his notes and feedback on their work could get nasty and personal.

Representatives from “The Tonight Show Starring Jimmy Fallon” did not respond when The Post reached out for comment.
