According to reports, Dempsey, the father of three, hit his breaking point and started acting out on the set of the show.
In an interview for the book, How to Save a Life: The Inside Story of Grey’s Anatomy (2021), Dempsey confessed to resenting the Grey’s schedule. “It’s 10 months, 15 hours a day. You never know your schedule, so your kid asks you, ‘What are you doing on Monday?’ And you go, ‘I don’t know,’ because I don’t know my schedule,” Dempsey said. “Doing that for 11 years is challenging. But you have to be grateful, because you’re well compensated, so you can’t really complain because you don’t really have a right.”
And, what happened early 2015 might explain his on-set behavior.
