on-call staff
Ready when needed
On-call staff are employees who aren't actively working but remain available to be summoned when needed.
Hospitals keep on-call staff for emergencies; IT departments have on-call staff for system failures.
The arrangement means being reachable and ready to report, often with restrictions on travel or alcohol consumption: Three nurses are on-call tonight.
