Sick Leave and Presenteeism

Absence is measured everywhere. Presenteeism — present but working at reduced capacity — is measured almost nowhere and frequently costs more.

Why low absence can be a bad sign

People working while ill recover slower, perform worse, spread infection, and make more errors.

It signals that absence is penalised, formally or informally.

It conceals the underlying rate, so the organisation believes it has no problem.

It predicts a later spike. Deferred recovery accumulates and eventually presents as long-term absence.

A very low absence rate in a demanding environment is worth investigating, not celebrating.

What drives presenteeism

Trigger-point policies that penalise a number of absence occasions, which encourage people to work through short illnesses and take longer ones.

No cover, so the work waits and returning is worse.

Insecure or unpaid arrangements, where absence has a direct financial cost.

Manager attitude, which sets the actual policy regardless of the written one.

Team guilt, where colleagues visibly absorb the load.

A culture of visible commitment, where attendance is read as dedication.

What attendance policies actually incentivise

Occasion-counting policies penalise frequency rather than duration. The rational response is to take fewer, longer absences.

Return-to-work interviews used as challenge rather than support teach people to avoid triggering them.

Absence in performance reviews makes illness a career matter.

Perfect attendance rewards explicitly incentivise working while ill and, in some settings, are a safety problem.

Before changing a policy, ask what behaviour it produces rather than what it intends.

Measuring properly

Short-term absence frequency, which is an earlier signal than total days.

Long-term absence, separately, since the causes differ.

Return patterns, particularly repeat absences from the same person or team.

Presenteeism, which requires asking. A single anonymous question — how many days in the last month did you work while unwell enough that you should not have — produces a usable figure.

Segment by team, as always. Clustering is the finding.

What helps

Cover that works, so absence does not create a debt.

Clear permission to be absent when ill, stated and demonstrated by senior behaviour.

Paid sick leave, which is the foundation and is not universal.

Return processes that support rather than interrogate.

Treating clustered absence as a management question about that team's conditions rather than as a series of individual conduct matters.

The connection to burnout

Chronic overload produces both — more illness, and more working through it.

The team that cannot afford anyone to be absent is the team with a staffing problem, and its absence figures will look excellent until they do not.

Absence data segmented by team, read alongside vacancy duration and hours worked, identifies pressure points earlier than any survey, using data the organisation already holds.

Measuring presenteeism

Nobody measures it and one question captures most of it.

In the last month, how many days did you work while unwell enough that you should have taken sick leave?

Anonymous, aggregated by team, asked alongside whatever else you survey.

Read it against the absence figures. Low absence with high presenteeism is the pattern that looks healthy and is not.

Segment it. Clustering identifies the teams where cover has failed or where the manager's attitude is the constraint.

Track it over time, because the direction matters more than the level.

Expect the number to be higher than leadership predicts, which is itself the useful part of the exercise.

What your attendance policy incentivises

Before changing a policy, work out what behaviour the current one produces.

Occasion-counting encourages fewer, longer absences.

Trigger points encourage working through short illnesses until something serious accumulates.

Absence in performance reviews makes illness a career matter and guarantees concealment.

Perfect attendance awards explicitly reward working while ill.

Ask what a rational employee would do under your policy. That is what they are doing, and it is usually not what the policy intended.
