In a January interview with TVLine, showrunner Andrea Newman explained the creative choices behind why characters such as Brett are departing the show

“Honestly, longevity is really just part of it. [In] storytelling and in terms of real life, 12 years is a long time and things need to change, just dynamic-wise. You want new characters and you want new dynamics.  Actor-wise, 12 years is a long [time]. Nobody expects in TV [that] they’re going to be anywhere for 12 years, I can say that for sure, from all sides,” she told the outlet. 

"To really get to arc these things out and see these characters change. But you need to mix it up. It can’t be the same the whole time. There’s still Boden at the helm and Severide and Kidd. It still feels very strong, and it still feels, because we’ll see Matt Casey, like most people who’ve been part of it are still part of it in lots of ways. So that’s lucky for us, too," she added.
