When you need to ask for last-minute coverage. The "no pressure" framing matters — staff are more likely to say yes when they don't feel cornered. Always offer something in return.
Hi {staff_first_name},
{coworker_name} called out for tomorrow ({date}), and I'm trying to cover {their_room_or_shift}. Is there any chance you could come in {time_window}?
