Nigeria’s statutory sick leave entitlement is 12 working days a year, and it comes with an important qualification most employers miss: the Labour Act does not apply to everyone. Its protections cover “workers” as the Act defines them — broadly manual labour and clerical roles — and expressly exclude those in administrative, executive, technical, or professional positions.

For the excluded majority of white-collar staff, sick leave is whatever the employment contract, staff handbook, or collective agreement says it is. That makes the contract, not the statute, the operative document for most Nigerian employers.

Key takeaways

Section 16 of the Labour Act (Cap L1, LFN 2004) entitles a worker to wages for up to 12 working days of absence in a calendar year caused by temporary illness.
The illness must be certified by a registered medical practitioner.
The Act’s protections apply to “workers” — it excludes those employed in administrative, executive, technical, or professional capacities.
For excluded employees, sick leave is governed by the contract of employment and company policy.
Work-related injury and disease fall under the Employee’s Compensation Act 2010, administered through the NSITF.

The 12-day entitlement

Section 16 provides that a worker is entitled to be paid wages for up to twelve working days in any one calendar year during absence from work caused by temporary illness certified by a registered medical practitioner.

Three elements matter:

12 working days, not calendar days — weekends and public holidays inside an absence do not consume the allowance.
Per calendar year, so the allowance resets on 1 January regardless of when the employee started.
Certified, so the entitlement to pay depends on a certificate from a registered medical practitioner.

There is no statutory service qualification. A worker in their first month is entitled to the same 12 days as one with ten years of service.

Unused days do not carry over and have no cash value on termination.

Who the Labour Act actually covers

The Act defines a “worker” as any person who has entered into or works under a contract with an employer for manual labour or clerical work, and then expressly excludes persons exercising administrative, executive, technical, or professional functions as public officers or otherwise.

The practical consequence: most managerial, professional, and senior technical staff in Nigerian companies are outside the Labour Act’s sick leave provision. Their entitlement is set by contract.

This is not a licence to offer nothing. Nigerian employment relationships are governed by the contract, and the National Industrial Court will enforce contractual and handbook terms — and will look at international best practice under section 254C of the Constitution where the contract is silent or the treatment is unfair. Most Nigerian employers therefore provide contractual sick leave well above 12 days, commonly in the range of two to four weeks.

Certification

The Act requires certification by a registered medical practitioner. Company policies typically set out:

The notification requirement — usually to inform the line manager on the first day of absence
The threshold at which a certificate must be produced
Whether the employer’s retained clinic or any registered practitioner may certify

Employers may reasonably require certification from a recognised facility, but a policy that only accepts certificates from a single named provider creates practical problems for employees travelling or based outside major cities and is difficult to enforce consistently.

Work injury: the Employee’s Compensation Act

Injury, disease, or death arising out of and in the course of employment is covered by the Employee’s Compensation Act 2010, administered by the Nigeria Social Insurance Trust Fund (NSITF).

Employers must contribute to the Employees’ Compensation Fund at the prescribed rate of total monthly payroll. The scheme provides:

Compensation for temporary total or partial incapacity, paid as a proportion of monthly remuneration
Medical expenses and rehabilitation
Permanent disability and death benefits for dependants

An employer must report a workplace accident to the NSITF and the nearest labour office within the statutory period. Charging a work injury against the 12-day sick leave allowance takes paid days from the employee that the Fund should be covering.

Long-term absence

Neither the Labour Act nor general Nigerian employment law provides a fixed protected period for prolonged illness. Beyond the statutory or contractual entitlement, absence becomes a capability question governed by the contract and handbook.

The National Industrial Court’s jurisdiction over unfair labour practice means process matters. Employers should follow their own disciplinary and capability procedures, document medical evidence and the alternatives considered, and give the employee an opportunity to respond before terminating. Termination that ignores the employer’s own handbook is a familiar route to an adverse NICN judgment.

Employer obligations

Nigerian employers have six core duties:

Pay wages for up to 12 working days of certified temporary illness per calendar year for employees covered by the Labour Act.
Apply the contractual entitlement for administrative, executive, technical, and professional staff outside the Act.
Accept certification from a registered medical practitioner and set the threshold clearly in policy.
Contribute to the Employees’ Compensation Fund and report workplace accidents to the NSITF.
Keep work injury absence separate from the sick leave allowance.
Follow the handbook’s capability process before terminating for prolonged illness.

Common pitfalls

1. Applying 12 days to everyone as a maximum

For Labour Act “workers” it is a statutory minimum. For everyone else the contract governs, and most Nigerian employers offer more. Treating 12 days as a company-wide ceiling both understates the contractual position and looks poor against market practice.

2. Counting calendar days

The allowance is 12 working days. Counting weekends inside an absence exhausts it roughly 40% faster than the Act allows.

3. Ignoring the coverage exclusion

Applying the Labour Act to a professional employee, or assuming the Act’s silence means no entitlement, both misread section 16. The contract is the reference for excluded staff.

4. Charging work injuries to sick leave

The Employee’s Compensation Act and the NSITF exist for that purpose, and the employer already contributes to the Fund.

5. Terminating without following the handbook

The National Industrial Court enforces the employer’s own procedures. Skipping them on a long-absence termination is the most reliable way to lose the case.

Frequently asked questions

How many sick days do Nigerian employees get?

The Labour Act provides up to 12 working days of paid sick leave per calendar year for employees it covers. Administrative, executive, technical, and professional staff rely on their contract, which commonly provides more.

Does the Labour Act apply to all employees?

No. It covers “workers” engaged in manual labour or clerical work and excludes those exercising administrative, executive, technical, or professional functions.

Is a medical certificate required?

Yes, for the statutory entitlement. The illness must be certified by a registered medical practitioner.

Does the entitlement carry over?

No. It is a calendar-year allowance with no carry-over and no cash value on termination.

What covers a workplace injury?

The Employee’s Compensation Act 2010, administered by the NSITF and funded by employer contributions. Work injury absence should not draw on the sick leave allowance.

Is there protection against dismissal for long-term illness?

There is no fixed statutory protected period, but the National Industrial Court will scrutinise whether the employer followed its own procedures and treated the employee fairly.

Putting it into practice

Five checks cover most Nigerian sick leave risk:

Classify each role as inside or outside the Labour Act’s “worker” definition and configure entitlements accordingly.
Set the statutory allowance in working days so weekends do not consume it.
Put the contractual sick leave entitlement in writing for staff outside the Act, rather than leaving it to custom.
Create a separate Employee’s Compensation absence type routed to the NSITF process.
Make the handbook’s capability process a required gate before any long-absence termination.

You can take advantage of the free 14 days trial and explore Leave Balance.

A leave management system that applies different sick leave rules to Labour Act workers and contractual staff, counts in working days, and keeps compensable work injury out of the ordinary allowance gives Nigerian HR a defensible record for both the labour office and the NICN.
