In Season 11, Elizabeth's dormant disdain for and disrespect of Kerry Weaver inexplicably returns when Elizabeth is angry that the hospital hired Dr. Lucien Dubenko to be a surgeon there, and Kerry is justly confused/irritated about Elizabeth's problems because Elizabeth cannot provide any valid anti-Dubenko arguments and doesn't understand why Elizabeth is "taking this so personally." A fed-up Elizabeth takes action in the episode "Try Carter" when she is convinced by Dr. John Carter to perform an illegal donation procedure between two HIV positive patients. Partly because she believes the operation is the right thing to do (she also notes that a bill legalizing organ transplants between HIV+ individuals was approved by the Illinois state legislature and is stuck in bureaucratic limbo so the Governor hasn't been able to sign it into law) and partly because she's angry at Kerry, Elizabeth does successfully perform the operation. This results in her facing the possibility of her losing her license and being dismissed from the staff. Weaver not unkindly but bluntly offers her the position of a clinical instructor with no possibility of tenure or future promotion. With her career all but over at County, Corday quits her job and moves back to England. Corday's final appearance as a series regular was in Season 11, episode 4 "Fear".
