Probation Periods: A Manager’s Guide

A probation period is the trial phase at the start of employment, a defined window, usually three to six months, during which both the employer and the employee assess whether the fit is right. Done well, it is one of the most useful management tools you have: a structured period for training, feedback, and honest evaluation. Done badly, it is a formality nobody takes seriously until it is too late to act.

This guide is for the manager running the probation, not the lawyer writing the contract. It covers how to set one up, how to manage someone through it, and how to make the final decision fairly.

A necessary note: probation rules, maximum length, notice requirements during probation, and what happens at the end, vary by country and sometimes by contract type. Check your local employment law before setting terms, and make sure the probation terms are written into the employment contract or offer letter from the start.

Why This Matters

Hiring is a bet. Interviews and references reduce the uncertainty, but you never truly know how someone performs until they do the job, in your team, with your customers, under your pressures. The probation period is the structured answer to that uncertainty.

For the employer, it provides a defined timeframe to assess competence, conduct, and cultural fit, with a clear decision point at the end. For the employee, it provides structured feedback and support while they learn the role, which is exactly what good hires want. A well-run probation does not feel like a threat; it feels like an investment in getting the person up to speed.

The cost of neglecting probation is familiar to every experienced manager: the underperformer who was “given more time” until they passed probation by default, and then became nearly impossible to manage. Almost every difficult long-term performance case traces back to a probation that was never really run.

Key Concepts

Probation is active, not passive

The most common misunderstanding: that probation is a waiting period after which you decide. In reality, probation only works if it is actively managed, with objectives set at the start, regular check-ins, documented feedback, and support where the person struggles. A manager who sets no objectives, holds no reviews, and then fails someone at month six has not run a probation; they have run a surprise.

The three things you are assessing

Strip away the paperwork and probation assesses three things:

Competence, can they do the work to the required standard?
Conduct, do they meet the behavioural expectations: reliability, attitude, teamwork, integrity?
Fit, do they work well within this team and this company’s way of operating?

All three matter. A brilliant technician who poisons team morale is a failed probation. A lovely person who cannot do the core tasks is also a failed probation. Be honest about all three from the start so the employee knows what is being measured.

Extension vs termination vs confirmation

At the end of probation there are three outcomes, and managers should understand all three before the period starts:

Confirmation, the person meets the standard; probation ends and employment continues.
Extension, progress is being made but more time is needed; the extension is defined, with specific objectives and a new end date. (Whether extensions are permitted and for how long varies, check your local employment law and the contract.)
Non-confirmation / termination, the standard has not been met despite feedback and support; employment ends with whatever notice the contract and local law require.

Extension is often the right call when the trajectory is positive but the timeline was too short. Termination is the right call when the gaps are fundamental and documented feedback has not closed them. The wrong call, the one managers make most, is silent confirmation by default: letting the date pass with no review, no decision, and no record.

Practical Steps: Running a Good Probation

1. Set it up before day one. The probation length, objectives, and review schedule should be in the offer letter or contract. The new starter’s first-week plan should include their probation objectives, three to five clear, measurable goals for the period. “Learn the ropes” is not an objective; “independently process customer returns following the returns SOP by week six” is.

2. Assign a buddy, not just a manager. A named colleague who answers the small daily questions (“where do we file this?”, “who approves that?”) accelerates settling-in enormously and surfaces problems the manager might not see.

3. Hold scheduled reviews, monthly at minimum. Each review covers: progress against objectives, what is going well, where support is needed, and any concerns, stated plainly and early. Write a brief record of each review and share it with the employee. No surprises at the final review, if termination is on the table at month six, the employee should have heard the concerns at months two and four.

4. Give feedback in real time, not just at reviews. Waiting for the monthly meeting to mention a problem wastes weeks. Address issues as they arise, kindly and specifically, and note that you did so. The review then becomes a summary, not a revelation.

5. Document everything. Keep a simple probation file: objectives, review notes, examples of good work, records of concerns raised and support offered. This file is what makes the final decision defensible, and it is also what makes feedback to the employee concrete instead of vague.

6. Decide before the end date. Diary the final review for two to three weeks before probation ends, leaving time to act on the decision. At the meeting, confirm, extend, or end, and communicate the outcome in writing the same week. Letting probation lapse without a decision is the single most common probation failure.

7. If it is not working, say so early. When the gaps are clear by month two and support is not closing them, do not wait until month six out of discomfort. An honest early conversation, “this is where you are against the objectives, this is what needs to change, and this is the support available”, is kinder than a sudden termination, and it sometimes turns things around.

Common Mistakes

No objectives. “We’ll see how it goes” is not a probation plan. Without written objectives, the final decision is subjective and indefensible.
The silent probation. No reviews, no feedback, no records, then a surprise decision. This fails the employee and exposes the business.
Moving the goalposts. Changing the objectives halfway through without discussion, or judging the person against standards that were never stated. Objectives can evolve, but changes must be communicated and recorded.
Confusing probation with a notice-free dismissal. Probation does not mean you can dismiss for any reason without process, the employee is still entitled to fairness, and in many jurisdictions to specific notice and procedural rights. Check your local employment law.
Extending indefinitely. One defined extension with clear objectives is reasonable. Rolling extensions with no end date are just avoidance, they leave the employee in limbo and the manager without a decision.
Keeping someone out of guilt. “They’ve been here five months, it feels harsh” is not a management reason. If the standard is not met and will not be met, extending the inevitable helps no one, least of all the employee, who deserves clarity.
No written confirmation. When probation is passed, confirm it in writing. It closes the loop, gives the employee confidence, and removes any ambiguity about their status.
