Google Sheets – Compare Two Lists and Find Non-Duplicated Names

I have one list of total available people and the second list of people who have been assigned. I would like to auto-populate a third list of the people (from the first list) who have not been assigned (list B). Basically whichever names from column A that are not used in Column B would show up in Column C.
