A statement, reprimand, or admonishment handed down to someone lower in the ranks of a work environment, mainly in the service industry or trades, especially in restaurant or bar service. Saying that they have to do the shitty work for the night. This is specially reserved for when the person is reprimanded and is doomed to serve the non-tipping customers for the night.
Nick: Eric, You showed up 20 minutes late for work. You're on shithead duty for the night. Serve table six their bread.

Eric: (Looks at the table of ten black customers) Damn, I'm not making any tips tonight. I'll never show up late to work again.
