Probation Periods in Nigeria: What Employers Can and Cannot Do

A probation period is the early stage of employment during which an employer assesses whether a new employee is suitable for a role. In Nigerian workplaces, probation often lasts three or six months, but the Labour Act does not prescribe a universal maximum probation length or make probation compulsory.

What matters most is the employment contract. The appointment letter, employee handbook, collective agreement where applicable, and statutory employment rules determine how probation works. A person on probation is still an employee: they work, earn salary, accrue applicable statutory rights, and remain entitled to the terms written in their contract.

For employers, probation is a structured evaluation period, not a legal blank cheque. For employees, it is not a period in which wages, notice, dignity, or contractual protections disappear.

Is probation compulsory in Nigeria?

No. Nigerian law does not require every employment contract to contain a probation clause. A probation period exists where the employer and employee agree to it through an appointment letter, employment contract, handbook incorporated into the contract, or another binding employment term.

The Labour Act, Cap L1, Laws of the Federation of Nigeria 2004, does not create a fixed three-month, six-month, or one-year probation period. Instead, it regulates employment contracts, written particulars, wages, working time, leave, and termination notice for workers covered by the Act. The National Industrial Court has also treated the agreed probation clause as important when deciding disputes over confirmation and termination.

In practice, many Nigerian organisations use:

The duration alone is not enough. A good probation clause identifies:

• The probation start and end dates
• The employee’s job title and reporting line
• Measurable performance, conduct, attendance, or training criteria
• Whether confirmation is automatic or requires written confirmation
• The applicable notice period during probation
• Whether payment in lieu of notice is permitted
• The process for performance reviews and documentation

Section 7(1) of the Labour Act requires an employer to provide written particulars of employment within three months of the start date. These particulars include the nature of the work, wage rate, payment method and frequency, termination notice period, hours, holiday terms, sickness arrangements, and special conditions.

What employers can do during probation

An employer can assess an employee’s suitability during an agreed probation period. That assessment can include the employee’s work quality, attendance, punctuality, ability to perform stated duties, conduct, customer service, training progress, and compliance with lawful workplace rules.

An employer can also take the following actions where the contract and applicable law support them.

Set measurable performance standards

A company may set reasonable probation targets. For example, a Lagos-based customer-support officer earning ₦180,000 monthly may have targets such as:

• Completing product and customer-service training
• Achieving a documented quality score
• Maintaining agreed work hours and attendance
• Handling customer records confidentially
• Meeting a stated response-time standard

These standards are clearer when communicated at the start of employment rather than introduced at the final review meeting.

Conduct probation reviews

Employers can conduct a 30-day, 60-day, 90-day, or other scheduled review, depending on the contract length. Review notes, attendance data, customer feedback, training results, and written performance discussions create a factual record of how the employee performed.

Documentation is particularly useful when the probation decision is disputed later. It also gives the employee a clear understanding of the areas assessed.

Confirm employment

Where the employee completes probation satisfactorily, the employer can issue a confirmation letter. The letter can state:

• The confirmation effective date
• The employee’s confirmed designation
• Any revised salary or benefits
• The notice period after confirmation
• Continued application of the staff handbook and workplace policies

A confirmation letter is not merely ceremonial. It gives both parties evidence of the employee’s status and the terms that apply after probation.

Terminate in line with the contract

An employer can terminate employment during probation where the contract permits termination and the employer follows the agreed notice or payment-in-lieu arrangement. The Labour Act’s default notice rules can apply to workers covered by the Act, while senior, managerial, technical, executive, and professional employees may be governed more directly by their specific contracts because of the narrower statutory definition of worker in Section 91.

In Mr. Olusola Idowu Bello v Pacific Diagnostics Limited, the National Industrial Court considered an employment term requiring one month’s written notice or payment in lieu during probation. The case illustrates a central point: the written contract remains important even during a probationary appointment.

What employers cannot do during probation

Probation does not erase statutory wage protections or allow an employer to disregard its own written employment terms. The following practices create legal and HR risk.

Keep extending probation indefinitely

An employer cannot safely treat probation as an open-ended status. In Ann Chiamaka Nwanguma v Artee Industries Limited & Ors, decided by the National Industrial Court in October 2024, the court held that the employee was deemed confirmed after the stipulated probation period elapsed and she continued in employment. The court rejected the attempt to keep the employee on probation beyond the agreed framework.

The decision is especially relevant where an appointment letter says, “six months probation,” but the employer continues to retain and pay the employee after six months without a timely confirmation or termination decision.

A practical distinction is useful:

The Court of Appeal authority discussed in the Nwanguma decision also supports the principle that retaining an employee and continuing salary payments after probation can amount to confirmation by conduct.

Withhold earned salary because an employee is on probation

A probationer earns pay for work performed. Section 15 of the Labour Act provides that wages become due at the end of the agreed payment period and, where that period exceeds one month, payment becomes due at intervals not exceeding one month.

For example, if an employee earns ₦150,000 monthly and works from 1 to 20 June before termination, the contract and payroll policy may require a pro-rated calculation:

[ \text{Daily rate} = \frac{₦150{,}000}{30} = ₦5{,}000 ]

[ \text{Pay for 20 days} = ₦5{,}000 \times 20 = ₦100{,}000 ]

The final payroll can also include lawful deductions and any applicable payment in lieu of notice. The calculation method depends on the contract, payroll cycle, and whether the employer uses calendar days or working days consistently. ToolBase’s Salary Calculator can help illustrate gross-pay and pro-rated salary calculations.

Make unlawful or unexplained deductions

Section 5 of the Labour Act restricts deductions from a worker’s wages. Apart from deductions allowed by law or validly authorised arrangements, an employer cannot simply deduct money as a punishment, “training cost,” uniform fee, customer loss, or alleged mistake. The Act also limits total monthly deductions from a worker’s wages to one-third, subject to the statutory wording and applicable exceptions.

A company that alleges an employee caused loss during probation still needs to examine the contract, evidence, due process, and applicable wage-deduction rules before altering payroll.

Ignore the notice requirement

Section 11 of the Labour Act states default notice periods based on length of service:

Notice of one week or more is required to be in writing under Section 11(3). Section 11(6) allows either party to waive notice or accept payment in lieu of notice. Under Section 11(9), payment in lieu is calculated using money wages, excluding overtime and other allowances.

An employment contract may provide a longer probation notice period, such as one week or one month. Where the contract gives the employee a more favourable notice entitlement, the employer’s own contractual promise remains significant.

Example: An employee earns ₦240,000 monthly and has completed four months of probation. The contract provides one week’s written notice or salary in lieu. Using a 30-day payroll convention:

[ \text{One week notice pay} = ₦240{,}000 \times \frac{7}{30} = ₦56{,}000 ]

The final figure may differ if the contract defines a different daily-rate method or includes specific salary components. The Notice Period Calculator can help HR teams document the calculation before preparing final payroll.

Penalise trade-union membership

Section 9(6) of the Labour Act prohibits contractual terms that make union membership or non-membership a condition of employment. It also prohibits dismissal or prejudice because of trade-union membership or lawful union activity in the circumstances identified by the Act. That protection is not suspended because an employee is on probation.

Treat probationers as outside workplace safety obligations

A person on probation can suffer a workplace injury just as a confirmed employee can. Employers retain workplace safety and duty-of-care responsibilities. In the Nwanguma case, the employee’s workplace-injury allegations formed part of the dispute, even though the court ultimately assessed the evidence presented for those claims separately.

Pay, leave, pension and tax during probation

Probation affects confirmation status; it does not automatically remove payroll obligations.

PAYE tax

A probationary employee receiving taxable employment income is generally processed through the employer’s payroll under the Pay-As-You-Earn system. The employer calculates and remits tax in accordance with applicable tax law and the relevant state tax authority’s requirements.

An appointment letter saying “probation” does not convert salary into tax-free income. Payroll records should clearly show gross salary, deductions, net pay, payment date, and statutory remittances where applicable.

Pension contributions

The Pension Reform Act 2014 established the contributory pension scheme for the public and private sectors. PenCom explains that organisations with fewer than three employees are outside the mandatory compliance threshold, while employees in organisations with three or more employees fall within the mandatory scheme framework, subject to the Act and applicable exceptions.

Probation is not, by itself, a blanket exemption from pension obligations. Employers can examine the Act, their workforce size, employment status, and payroll records when determining treatment.

Sick leave and annual holiday

For workers covered by the Labour Act, Section 16 provides for wages for up to 12 working days in a calendar year for temporary illness certified by a registered medical practitioner, subject to the conditions in the section. Section 18 provides annual holiday entitlement after 12 months of continuous service: at least six working days with full pay, or 12 working days for a person under 16.

Since a six-month probationer has not yet completed 12 months’ continuous service, the annual-holiday entitlement under Section 18(1) has not yet matured. However, an employer may provide more generous contractual leave terms, and those written terms remain relevant.

A compliant probation process

A practical probation process has a beginning, evidence-based reviews, and a clear outcome. It is easier to administer when HR, payroll, and line managers use the same dates and documentation.

1. Issue an appointment letter stating the probation length, salary in naira, performance criteria, notice arrangement, work location, and effective start date.

2. Give the employee access to the staff handbook, policies, working-hours rules, confidentiality requirements, and grievance procedure.

3. Document induction, training, goals, attendance, feedback, commendations, warnings, and any performance-improvement discussions.

4. Conduct a review before the probation end date rather than after it has already expired.

5. Record one outcome: confirmation, termination in accordance with the contract, or another lawful contractual arrangement agreed before expiry and assessed against current case law.

6. Process final salary, lawful deductions, notice pay where applicable, tax records, and pension-related records accurately.

7. Give the employee written communication of the decision and retain the relevant HR documents securely.

Key takeaway

Probation in Nigeria is mainly a contractual employment arrangement, not a period without legal protections. Employers can assess performance, confirm employment, or end employment under the agreed terms. They cannot safely withhold earned wages, disregard notice obligations, make unlawful deductions, use probation as an indefinite status, or ignore the rights that apply to employees at work.

The strongest probation documentation is simple: a clear appointment letter, measurable review criteria, dated performance records, timely confirmation or termination communication, and accurate final payroll.
