Clopening

A chiefly US term for working a closing shift late at night and an opening shift the next morning, with only a short break between them.

The UK has no standard local name for it, but the practice exists in hospitality, retail, and event work. The legal issue is the 11-hour daily rest rule between working days. That turns a true clopening into a working-time compliance question, not just a bad scheduling habit.
