on call
Ready if needed
On call describes someone available to work or respond when summoned, even outside regular hours.
Doctors, IT technicians, and emergency personnel frequently work on call, ready to be contacted if needed: She's on call this weekend, so we can't go out of town.
The phrase implies obligation without active duty—waiting rather than working.
