on-call
Available if needed
On-call describes someone required to be available for work if needed, though not actively working: She's on-call this weekend, the on-call physician.
The term implies readiness to respond quickly—you can't travel far or drink heavily when you're on-call.
It applies especially to doctors, nurses, IT support, and emergency personnel.
