McBrayer's character Kenneth was fired in the last season finale but Carlock told Entertainment Weekly that he will manage to get his job back.
"We haven't cracked how he is getting back, but of course he will get back somehow," he said.
"We just wanted a fun thing to shuffle the deck a little bit and send him off into the world. Of course, he will miss it and he will be missed. Events will bring him back."
Julianne Moore recently revealed that she would love to return to the show.
