A manager approves time off, then asks the employee to keep an eye on messages because only they know a critical process. The approval and the work arrangement are saying different things. Coverage needs a decision before the absence begins.
List what cannot wait
Identify the genuinely time-sensitive tasks during the planned leave. Separate them from work that can pause or move. Do not assume that every recurring report or routine request must continue unchanged.
For an invented team, a daily service check may need a trained substitute, while a monthly internal presentation can be rescheduled. Treating both as equally urgent makes the coverage plan larger than necessary.
Give the substitute a realistic load
Name the person covering each essential task and confirm that they have the access, instructions and authority required. Review what should be removed from their ordinary workload. Adding a second job to an already full schedule is not a complete handover.
Arrange a short rehearsal for an unfamiliar process while the regular owner is available. Store the instructions in an approved shared location rather than in private messages that the substitute cannot search later.
Agree the contact boundary
State who handles unexpected problems and how escalation works. Respect the organisation’s policy, local employment requirements and the person’s agreed leave. Avoid an unspoken expectation that the absent colleague remains the default emergency service.
Where exceptional contact arrangements are genuinely needed and lawful, make them explicit rather than relying on guilt or habit. Ordinary inconvenience should not automatically become a reason to interrupt leave.
Review the return as well
Keep a brief record of significant decisions and unresolved work so the returning employee does not reconstruct the absence from dozens of separate conversations. Thank the people who covered the work and ask what proved difficult.
If the same single-person dependency appears every time someone takes leave, address it through training and process design. The lasting improvement is a team that can keep essential work moving while people are actually away, not merely marked away on the calendar.
