On-Call Shift Swaps and Cover: A Simple Policy
Schedules assume that everyone is available. They are not. A clear, simple swap policy keeps the pager covered without leaving the schedule disagreeing with reality.
People fall ill, travel, attend weddings and need sleep. Every on-call schedule needs a way to change who answers for a period without rewriting the rotation. The mechanism is usually called an override. The danger is the informal alternative: two colleagues agree in chat to swap, the schedule does not change, and the page goes to the wrong person.
A simple policy
- Swaps are allowed and encouraged. Nobody should have to choose between covering a shift and attending something important.
- Arrange the swap yourself, with the person who will cover. Ask early, and offer a swap in return.
- Record every swap in the schedule before it takes effect. A swap not in the system does not exist.
- Tell the team lead for any change within a set short notice, such as 48 hours, so that they can check cover.
- If you cannot find cover, escalate to the team lead, who is responsible for ensuring the period is covered.
- For sudden absences, the person who is unwell tells the team lead, who arranges cover and records it.
What an override should record
A good override has a start, an end, the person who will answer and a short reason. In Atlas an override carries those and changes who answers for the period. The rotation resumes afterwards, so there is nothing to put back.
An override can also state that nobody is on call for a stretch. This is useful for a planned gap during which you accept the risk, for instance a short period when the service is in maintenance. The point is that the gap is deliberate and visible, instead of falling through to a person who arranged not to be paged.
Spotting holes
Review the next two weeks regularly. A hole appears when someone leaves, when an override ends later than the swap and when a holiday overlaps. Atlas draws uncovered stretches in the band on the On call page and lets you put someone on from the lane where the hole is, so the check takes seconds.
Fairness
Swaps should not become a way for the same people to carry the unpleasant shifts. Look at who covers holidays and weekends over a quarter, and adjust the rotation or compensation if the burden falls unevenly.
