[Next to the sign-up sheet in the lobby is a time table, listing schedules for three shifts each night. 8:00-11:20, 11:20-2:40, 2:40-6:00. There's names written in and noticably there's no woman paired by with another woman, even though there's a few pairings of double men. Rarely there's someone solo.
This same schedule is uploaded onto the forums, showing that Luther would be taking first solo watch at 8, Micah and (someone if they want or he's solo?) at the 11:20, and 1206 and 1106 will be taking on the 2:40.
Filling in otherwise is up to players, plotting, etc. If your character has a complaint about an 'assignment', they can reply here?
