What is a probation period?

A probation period is a short‑term arrangement that lets an employer evaluate a new hire’s performance, attitude and fit with the team. During this time the employee works under the same basic terms as a regular staff member, but the contract usually contains a clause that allows either side to end the relationship with shorter notice.

Think of it as a two‑way test drive. The employer checks whether the employee can meet the job’s demands, while the employee decides if the role, culture and compensation meet expectations.

Maximum duration allowed by law

The Nigerian Labour Act does not prescribe a fixed number of days for probation. Instead it leaves the length to the contract, as long as the period is reasonable. Courts have repeatedly held that a probation that lasts longer than six months is likely to be seen as excessive unless there is a clear justification.

In practice most organisations set a probation of three months for entry‑level positions and six months for senior or technical roles. Extending beyond six months usually requires a written amendment that explains why extra time is needed – for example a long training programme or a phased handover.

Important: If a contract states a probation of more than six months without a solid reason, a court may treat the extra time as a breach of the employee’s right to a fair contract.

Employee rights while on probation

Even though you are on probation, you enjoy many of the same statutory protections as a permanent staff member. Here are the key rights you should keep in mind:

• Paid leave – you accrue annual leave from day one, though you may need to use it before the probation ends.
• Salary – the agreed wage must be paid on time, and any overtime should follow the same rules as for regular staff.
• Health and safety – the employer must provide a safe working environment and any required protective equipment.
• Non‑discrimination – you cannot be treated unfairly because of gender, religion, ethnicity or other protected characteristics.
• Termination notice – the contract may allow a shorter notice period, but it cannot be less than one day for a contract of less than three months, and one week for contracts longer than three months.

Tip: Ask for a written copy of the probation clause before you sign. It should spell out the length, performance criteria and the notice required for termination.

How confirmation works

When the probation period comes to an end, the employer should follow a clear confirmation process. The steps below are common in Nigerian companies:

1. Performance review – The line manager completes a written assessment that covers key targets, attendance, teamwork and any training completed.
2. Feedback meeting – The employee meets with the manager to discuss the review. Positive points are highlighted and any gaps are noted.
3. Decision notice – If the employee meets the standards, the employer issues a confirmation letter stating the new status, any salary adjustments and the effective date.
4. Contract amendment – The original contract is updated to remove the probation clause and to reflect any changes in benefits.

If the review shows that the employee has not yet met expectations, the employer may either extend the probation (with a written agreement) or end the employment. Extending should not push the total probation time beyond six months unless a valid reason is documented.

Common pitfalls and how to avoid them

Unclear performance criteria

Many disputes arise because the employee never knew what was expected. A good practice is to set measurable goals at the start – for example “complete the onboarding module within two weeks” or “handle at least five client calls per day”.

Missing written confirmation

Even if the manager says “you are now a permanent staff member”, the employee should ask for a written confirmation. This protects against future claims about salary or benefits.

Extending probation without justification

Extending beyond six months without a clear training plan can be challenged in court. If you need more time, ask for a detailed amendment that outlines the extra steps you will take.

Check list before your probation ends:

• Review your written performance goals.
• Ask for a copy of the manager’s assessment.
• Confirm the notice period required for either side.
• Secure a written confirmation letter.

Frequently asked questions

Can an employer change my salary during probation?

Yes, as long as the change is documented in writing and does not breach any minimum wage laws. However, many companies keep the salary fixed until confirmation to avoid confusion.

Do I get paid for annual leave accrued during probation?

Yes. If your contract ends before you have taken the leave, the employer must pay you for the accrued days at your normal rate.

What if I receive a termination notice that seems too short?

Check the probation clause in your contract. If the notice is shorter than the minimum required by law, you can raise the issue with HR or seek advice from the Labour Department.

Conclusion

Probation periods in Nigeria are meant to be a fair trial for both parties. The law expects the duration to be reasonable – typically three to six months – and requires that employee rights such as leave, pay and safety are respected throughout. A transparent performance review, written confirmation and a clear contract amendment are the hallmarks of a smooth transition to permanent employment.

If you are about to start a new role, take the time to read the probation clause carefully, ask for measurable goals and keep a record of any feedback you receive. Doing so will give you confidence that the trial period works for you, not against you.
