How to arrange teacher cover when someone calls in sick
It is 8 a.m., a teacher has called in sick, and three of their periods now belong to nobody. Sorted badly, it eats your morning and lands on whichever teacher happens to be standing in the corridor. Sorted well, it is settled before the bell and shared fairly. Here is how to get there.
Genuinely free this period, ranked
The short version
- Cover only from teachers who are genuinely free that exact period.
- Share the load so the same helpful few are not always pulled in.
- Leave the cover teacher a task, so the class learns and does not just wait.
- Keep a record of who covered what, for fairness and for pay.
Doing this by hand every morning is the slow part. Let the timetable suggest fair cover in seconds.
Find who is genuinely free, not just who is around
The first instinct is to grab the nearest available teacher. The trouble is that “available” and “genuinely free this period” are not the same thing. A teacher might be on a free period on paper but already booked for a remedial group, a duty, or a club. Start from the real timetable for that exact period and you avoid pulling someone who was never actually free.
- Check the period, not the day. Free at 9 does not mean free at 11.
- Exclude teachers already on duty, exam invigilation or a fixed commitment.
- Prefer a teacher of the same subject for senior classes where it matters.
Share the load so the same people are not always pulled in
Every staffroom has two or three teachers who never say no. Lean on them and you burn them out and breed quiet resentment. Fair cover means looking at who has already covered this week and who is carrying a heavy teaching day, then spreading the next one to someone lighter.
Cover that is shared fairly is the difference between a staffroom that helps willingly and one that hides when the 8 a.m. call comes in.
Give the cover teacher something to actually do
A class with no work set is a class that learns nothing and gets restless. The absent teacher, or the head of department, should leave a simple task: a worksheet, reading, or revision tied to where the class actually is. The cover teacher then supervises and helps rather than improvising a lesson cold. Keep a short note of who covered which class, so the record is there for fairness and for any cover pay.
Let the timetable do the matching
Finding who is genuinely free, ranking them by subject fit and lightest load, and keeping it fair is exactly the kind of work software does in a second. With ZeroClash, you mark a teacher absent and get a ranked list of the teachers who are truly free that period, with the reason shown for each. Assign in one click and the covering teacher gets an instant alert, so cover is sorted before students arrive and the load stays evenly spread.

Frequently asked questions
What is the fairest way to choose a cover teacher?
Pick from the teachers who are genuinely free that period, then favour whoever is carrying the lightest cover load that week and is not already on a run of back-to-back periods. Rotating it this way stops the same two or three helpful teachers from quietly carrying everyone.
How quickly should cover be sorted in the morning?
Before the first bell. If the absence is known by the 8 a.m. call, the cover teacher should know which class and period they are taking, and the work to set, well before students arrive. The slow part is finding who is free, which is exactly what software removes.
Should a cover teacher teach the subject or just supervise?
Either works as long as it is planned. For senior classes a subject-matched cover is ideal. For most periods, a clear task left by the absent teacher keeps the class learning rather than idle, so the cover teacher only has to supervise and help.
