picket duty
Protest line assignment
Picket duty is the assignment of soldiers or guards to a picket—a forward position where they watch for enemy movement and provide early warning.
The term extends to labor disputes, where picket duty means taking a shift on the picket line: I've got picket duty at the plant gate tomorrow morning.
