Double-back 

Working closing shift, say 4PM to Midnight, only to have to be back early in the AM. Common among convenience stores, and police departments.

Man, I'm wiped. Worked Swing shift last night, had to double-back to the Physical Fitness test this morning. NOTHING beats a timed run on 4 hours' sleep...
