Two Hours Short on the Roster
You supervise a team of 12 custodial officers across a 24-hour period. Each officer is contracted for 8 hours, and the roster requires a minimum of 4 officers on duty at all times. Three officers call in sick for the same night shift (22:00–06:00). Available cover options are:
- Officer A: can work a double shift (16 hours), but has already worked 9 hours today.
- Officer B: is rostered off but has indicated availability; would need 3 hours' notice and lives 45 minutes away.
- Officer C: is on annual leave; local policy permits recall only for emergency staffing below minimum safe levels.
- Overtime budget remaining for the week: 14 hours.
Current confirmed coverage for the night shift is 2 officers. You need to reach the minimum of 4.
1. Calculate the gap and identify the minimum additional hours required to cover the night shift, showing your reasoning.

Gap: minimum 4 on duty; 2 confirmed → 2 officers short for an 8-hour shift = 16 officer-hours required.
Options against the 14-hour overtime budget:
- Officer A double shift: A has already worked 9 hours, so a 16-hour shift would take them to 25 hours in the period. Even setting aside fatigue and likely policy limits on maximum shift length, the additional hours needed to cover the night are 8 - but A is already at 9 hours, so this breaches reasonable shift-length limits and is unsafe for a role requiring alertness. Not the preferred option.
- Officer B: 8 hours, within budget, and no fatigue concern. Covers one of the two gaps.
- Officer C: recall from leave; 8 hours, but uses the emergency provision and consumes budget.
Best first move: confirm Officer B (8 hours). That leaves one officer / 8 hours to fill, within the remaining 6 hours of budget only if a partial option exists - so B plus a partial recall or a shorter double for A (e.g., 6 hours) may be needed. The arithmetic shows B alone is insufficient and A's full double is the weakest option on safety grounds.
2. Between recalling Officer C from annual leave and asking Officer A to work a double shift, which is the better decision, and what factors drive it?
Read the worked answer
Recall of Officer C is generally the better option, provided the policy threshold ('below minimum safe levels') is genuinely met - and here it is, since coverage is below the required minimum.
Driving factors:
- Safety and fatigue. A would reach 25 hours worked. A custodial role demands sustained attention and sound judgement; a fatigued officer is a risk to themselves, colleagues, and detainees. Fatigue-related error is a foreseeable harm.
- Policy fit. Officer C's recall is explicitly authorised for exactly this situation. Using the sanctioned mechanism is defensible; stretching A beyond safe limits is not.
- Predictability. C is rested and can work a full 8 hours, closing the gap cleanly rather than partially.
Counterweights to acknowledge: recall disrupts C's leave and affects morale; it may carry cost or entitlements. These are real but secondary to safe staffing. A partial, shorter extension for A could be considered only as a last resort and only within shift-length policy.
3. What should you communicate to the team, and in what order, once the decision is made?
Read the worked answer
Sequence matters - people act on the first clear message.
- Confirm the gap is closed first. Contact Officer C (and B) and get firm acceptance before announcing anything, so you are not walking back a commitment.
- Brief the oncoming night shift with the confirmed staffing, any changed post assignments, and who is in charge. Operational clarity first.
- Notify the supervisor/manager of the shortfall, the action taken, and the overtime/leave impact - this is a reportable staffing event, not something to absorb quietly.
- Speak to Officer A directly and privately to explain why the double was not used (fatigue risk, not a judgement of their commitment). This protects the relationship and avoids the impression they were passed over.
- Record it - roster change, reason, approvals - so the decision is auditable and the pattern (three simultaneous sick calls) can be reviewed.
