What probation period means
Probation is a trial period written into the employment contract.
Both sides are testing the fit. The employer is deciding whether to confirm the employee, and the employee is deciding whether to stay. Notice periods during probation are usually shorter, which is the main practical difference.
What probation is not is a rights free zone. Employers frequently behave as though a probationer can be treated any way at all, and that is simply not the position.
How it is used
The contract states the length, commonly three to six months, and what happens at the end. Confirmation should be in writing. Extension, where the contract allows it, should also be in writing and for a stated period.
The most common failure is silence. Probation expires, nobody confirms anything, and the employee carries on working for another year. At that point arguing they are still on probation is unconvincing, because the conduct of both parties says otherwise.
Key features
- Set by the employment contract rather than by statute
- Commonly three to six months, sometimes extendable if the contract allows
- Usually carries a shorter notice period on either side
- Should end with written confirmation, extension or termination
- Does not remove statutory protections or the right to be paid correctly
How this works in Nigeria
There is no Nigerian statute fixing a maximum probation period, which is why employers set their own. The National Industrial Court has, however, been unimpressed by employers who use probation as cover for arbitrary treatment or who leave staff on rolling probation indefinitely.
Employees on probation are entitled to their agreed salary, to statutory deductions being handled properly, and to a process that is not capricious. An employer who dismisses a probationer for alleged misconduct without any process is exposed in the same way as with a confirmed employee, even though ending probation for poor fit is much simpler.
Probation vs confirmed employment
The core difference is ease of exit. During probation, notice periods are shorter and the employer can end the relationship for fit rather than for cause.
After confirmation, notice is longer and the employer has more to justify, particularly where the exit is framed as dismissal for misconduct.
What does not change is that the employee is an employee throughout. Salary, agreed benefits, statutory contributions and the basic requirement of fair treatment apply from the first day, not from the confirmation letter.
Limits and risks
Probation cannot be used to avoid paying agreed salary or to withhold statutory contributions.
It also cannot run forever. An employee kept on probation for years, with no confirmation and no extension, will generally be treated as confirmed by conduct, and an employer relying on the original clause is likely to lose that argument.
Worth knowing
Confirm in writing on time. An employer who lets probation lapse silently has effectively confirmed the employee, and can no longer rely on the shorter notice period.
