At the bakery, the fat old baker sleeps while his apprentice rubs the flour out of his eyes, seated beside him.
The baker is sleeping because he works a different shift than his apprentice.
The baker and apprentice may work a different shift from one another or not.  Work schedules are not addressed  when one person sleeps and another rubs his eyes.
