No call, no show
No call, no show (English) — Sometimes even used as a noun to describe the person doing it. It means that someone failed to call in via telephone, or to appear in person at a place they were expected to be. Most businesses consider this to be a terminable offense. You will be sacked, fired.
It's used to describe an unreliable person in the workplace. Usually when others must stay over as a result.
