PagerDuty's calendar will automatically distribute on-call shifts evenly between layer members based on the rotation type and the selected starting point. Adding restrictions to a layer creates limitations on the times or days to which the schedule applies. By default, during a shift each person is on on-call duty continuously (24 hours a day, 7 days a week). However, you can restrict the on-call duty by adding restrictions to your on call schedule.
To add restrictions to a schedule:
Go to the Configuration menu and select Schedules.
Click on the schedule to edit, then click Edit this Schedule.
Select the Restrict on-call shifts at specific times checkbox to limit on-call duty to specific hours in the day.
Select Restrict on-call duty to specific times-of-the-day or Restrict on-call duty to specific times-of-the-week.
Set the from and to time and, if necessary, the day of the week, to restrict the on-call schedule to only apply during that time.
In the example below, we restricted the on-call user to be on call from 19:00-07:00 every weekday.
Note: Restricting on-call duty to specific dates and times creates gaps in schedule coverage. These gaps can remain unfilled, as with after-hours schedules. The gaps can also be filled with other layers, as in follow-the-sun or weekend/weekday schedules. Once the restrictions are set, the final schedule will show that the user is only on call from 19:00-07:00 every weekday. No one is on call from 07:00-19:00 or at any time during the weekend unless a second layer is created.
