Leave is treated in most organisations as an administrative matter: a form, an approval, a balance. It is actually two things at once — a financial liability sitting on the balance sheet, and the single clearest early indicator of who is heading for burnout.
Why untaken leave is a problem, not a virtue
An employee who does not take leave is often praised for commitment. What is actually happening is usually one of three things: the workload cannot absorb their absence, nobody else can do their job, or they believe taking leave will count against them.
All three are organisational failures, and all three carry cost. Accrued leave is a liability that grows and eventually has to be paid or taken. Someone who never takes leave is heading for a period of poor performance or a sudden extended absence. And a role only one person can perform is a business continuity risk sitting quietly in the corner.
Plan leave annually, not request by request
The most effective single change is to plan leave for the year rather than approving it in fragments. Early in the year, each team maps out roughly when people intend to take their entitlement.
This achieves three things at once: it spreads absence so the work stays covered, it reveals clashes while there is time to negotiate, and it converts leave from a favour that must be requested into a plan that already exists.
Control carry-over deliberately
Unlimited carry-over is how organisations end up with an employee holding two months of accrued leave and a liability nobody budgeted for. Set a clear limit, state the deadline by which the balance must be used, and — the part that is usually missing — make managers accountable for their team's balances.
Where carry-over has already built up, forcing it all to be taken at once creates the coverage crisis you were trying to avoid. A phased plan over a few months works better than a deadline nobody can meet.
Cover is the manager's job, not the employee's
The most common reason leave goes untaken is that the person cannot see who would do their work. When arranging cover falls entirely to the individual, many quietly conclude it is easier not to go.
Cover arrangements belong to the manager, planned in advance, and they double as cross-training: a colleague who has covered a role for two weeks is a genuine contingency for the rest of the year.
Sick leave tells you something too
Patterns matter more than totals. Frequent short absences, or absence concentrated in one team, are worth understanding rather than policing. The cause is sometimes health, and sometimes workload, a conflict, or conditions on site.
A return-to-work conversation after any absence — brief, supportive, not an interrogation — is the single most useful practice here. It shows the absence was noticed, and it surfaces problems that would otherwise repeat.
What the records must support
- Entitlement, taken and remaining, per employee, current at any time
- Approvals recorded, with dates
- Carry-over tracked against the policy limit
- The accrued liability, visible to finance rather than discovered at year end
Spreadsheets manage this until they do not. The failure point is usually the same: two versions in circulation and no agreement on which is current.
The signal worth watching
Once a quarter, list everyone who has taken no leave in the past six months. It is a short list, it takes minutes to produce, and it is the most useful wellbeing report most organisations never run. Almost everyone on it is either overloaded, irreplaceable, or afraid to go — and all three deserve a conversation.
