What sick leave means
Sick leave is time off work because of illness, with pay.
The Labour Act provides an entitlement for workers within its scope. A worker is entitled to be paid wages for absence caused by temporary illness for up to twelve working days in a calendar year, where the illness is certified by a registered medical practitioner.
Those three conditions all matter. The absence must be caused by temporary illness. It must be certified by a registered medical practitioner. And the statutory entitlement is limited to twelve working days in the year.
That is a floor rather than a norm. Most structured Nigerian employers provide more, through the contract or the staff handbook, and senior employees whose terms are governed by contract rather than by the Act rely entirely on what was agreed.
What the framework does not provide is an open ended entitlement. Illness lasting beyond the entitlement raises different questions about capability and about the contract.
How it is used
A workable sick leave policy in a staff handbook addresses a short list.
The entitlement: how many paid days, and whether it is more than the statutory minimum.
Notification: when and how an employee must tell the employer they are unwell, usually on the first morning and to a named person.
Certification: from what point a medical certificate is required, commonly after a stated number of consecutive days, and what the certificate must show.
What happens beyond the entitlement: unpaid leave, use of annual leave, or a capability process.
How sickness during annual leave is treated.
And the interaction with the employee compensation framework, where the illness or injury arose out of and in the course of employment, in which case the statutory scheme rather than sick pay is the route.
For employees, the practical advice is to notify early, obtain the certificate where the absence continues, and keep a copy. Absence that was never notified and never certified is the absence an employer treats as unauthorised.
Key features
- Paid absence for temporary illness
- The Labour Act provides up to twelve working days a year for workers within its scope
- Certification by a registered medical practitioner is required
- Contracts and handbooks commonly provide more
- Senior employees rely on their contract rather than the Act
- Work related illness engages the employee compensation framework instead
How this works in Nigeria
The Labour Act entitlement applies to workers within its definition, which broadly covers manual and clerical staff and excludes those exercising administrative, executive, technical or professional functions.
That exclusion matters. A senior professional employee has no statutory sick leave entitlement at all and relies entirely on the contract. Where the contract is silent, the position is negotiated rather than established, which is a poor place to be when you are unwell.
So the practical advice for employees is to check the contract at offer stage rather than at the point of illness.
For employers, the recurring difficulty is long term absence. An employee who exhausts the entitlement and remains unwell presents a capability question rather than a disciplinary one. Terminating for long term illness without a fair process, medical evidence and consideration of what accommodation is possible, is exposed at the National Industrial Court in the same way any other termination is.
The court expects a valid reason and a fair process, and long term ill health can be a valid reason where it is genuinely handled: obtain medical evidence, consider whether the employee can return with adjustments, keep the employee informed, and act only when the position is clear.
The disability dimension should also be considered. The Discrimination Against Persons with Disabilities (Prohibition) Act 2018 is relevant where a condition amounts to a disability, and an employer treating a disabled employee less favourably is exposed under that framework as well.
And where the illness or injury arose from work, the employee compensation scheme administered by the Nigeria Social Insurance Trust Fund is the route rather than ordinary sick pay.
Sick leave vs annual leave vs employee compensation
Three ways an employee is paid while not working, arising differently.
Sick leave is paid absence for illness, with a statutory floor under the Labour Act for workers within its scope and whatever the contract adds above that.
Annual leave is paid holiday, accrued by service, and it is the employee's to take subject to the employer's scheduling. It is not a substitute for sick leave, and requiring an employee to take annual leave when they are ill is poor practice even where the handbook permits it.
Employee compensation applies where the injury or illness arose out of and in the course of employment. It is paid through the scheme administered by the Nigeria Social Insurance Trust Fund, funded by employer contributions, and it does not require proof of fault.
An employee injured at work should be directed to the third rather than being told to use the first or second.
Limits and risks
The statutory entitlement is modest and it does not cover long absences.
It also does not apply to employees outside the Labour Act's definition of worker, which leaves most professional and managerial staff dependent on their contracts.
Where a contract is silent, there is no default entitlement to fall back on.
Enforcement also depends on the employee raising it, and an employee unwell and worried about their job rarely does.
And long term illness ultimately raises a capability question that sick leave does not answer, however generous the policy.
Worth knowing
Check the sick leave provision in your contract at offer stage. Most Nigerian professional and managerial employees fall outside the Labour Act entitlement entirely, and a contract that says nothing about sickness leaves you negotiating at the worst possible time.
Questions people ask
How much sick leave am I entitled to in Nigeria?
The Labour Act provides up to twelve working days of paid absence in a year for temporary illness certified by a registered medical practitioner, for workers within its scope. Contracts commonly provide more.
Does the Labour Act apply to me?
It applies to workers within its definition, broadly manual and clerical staff, and excludes those exercising administrative, executive, technical or professional functions. Senior employees rely on their contract.
Do I need a medical certificate?
The statutory entitlement requires certification by a registered medical practitioner. Handbooks usually specify from what point a certificate is required, commonly after a stated number of consecutive days.
What happens if I am ill for a long time?
Beyond the entitlement it becomes a capability question. An employer must obtain medical evidence, consider whether you can return with adjustments, keep you informed, and follow a fair process before acting.
Can my employer make me take annual leave when I am sick?
It is poor practice even where a handbook permits it. Annual leave and sick leave answer different needs, and an employee injured at work should be directed to the employee compensation scheme instead.
What if my illness was caused by work?
The employee compensation framework administered by the Nigeria Social Insurance Trust Fund applies, which compensates without proof of fault. That is the route rather than ordinary sick pay.
