I never mentioned a reason, only an answer. You'd have to take the "reason" with a grain of salt anyways, since it would have passed through enough political and rhetorical filters between the original thought and the words it was put into that you'd never be able to tell what was really meant anyways. They'd give you a paragraph of nonsense when the original reason was "The leprechauns who tell me to burn things say that Unne is the Devil."

Also, considering that staff jobs are unpaid, volunteer work, "I don't want to do this anymore" is a perfectly valid and unassailable reason to quit.
