"One Tree Hill" star Sophia Bush was the leading lady on "Chicago P.D." from 2014 to 2017, until she abruptly left, leading her character, Erin Lindsay, to have a slightly underwhelming departure. In the script, the only drama was that she left for a job in New York without saying goodbye to her partner, Jay Halstead (Jesse Lee Soffer). However, behind the scenes, things were much more intense.

"I quit because ... I've been so programmed to be a good girl and to be a workhorse and to be a tugboat that I have always prioritized tugging the ship for the crew, for the show, for the group, ahead of my own health," Bush explained on Dax Shepard's "Armchair Expert" podcast. "There were aspects of it that I loved ... [but] I was really, really unhappy."

The actor also alleged that she was assaulted on set in a room full of men who turned a blind eye to what was happening. Bush knew she had to leave, but was only four years into her seven-year contract. She gave a 23-episode notice, but it allegedly didn't go down well. "I said, 'OK, so you can put me in the position of going quietly of my own accord or you can put me in the position of suing the network to get me out of my deal and I'll write an op-ed for The New York Times and tell them why,'" she explained.
