Section 01
What a probation period is for
A probationary period is a defined window at the start of employment when both sides confirm the fit is right, usually with a shorter notice period on either side. Lengths commonly run from one to six months depending on the country, the contract and the seniority of the role. It is not a trial with fewer rights: most employment protections apply from day one in most jurisdictions, and the ones that do not vary enough by country that assuming is dangerous.
The purpose is worth being precise about, because a vague probation is worse than none. It is a commitment to reach a decision by a date, using evidence gathered on purpose. That framing changes what happens in the first months: it means expectations set explicitly at the start, feedback given while it can still change the outcome, and a conversation at the end that neither side is surprised by. Probation used as a formality achieves none of this and still costs everyone the notice period.
Section 02
Set the terms before day one
Four things belong in writing before the person starts, and all four are cheap then and expensive later. The length of the period and the exact end date. The notice period that applies during it, for both sides. What success looks like in specific terms, meaning the things that will be true if this is working, not a list of duties. And when the reviews will happen, with dates rather than intentions.
The success criteria are where most probations quietly fail. Written as a job description, they measure nothing, and the end of probation becomes a general impression. Written as observable outcomes, at a level appropriate to how new the person is, they let both sides see where things stand mid way through. A useful test: if the person could not tell you what would make the answer no, they cannot act on it, and a probation they cannot act on is a decision made about them rather than with them.
Section 03
Review while it can still change something
A single review at the end is not a probation process, it is an announcement. Reviews placed at roughly a third and two thirds of the way through leave time to act on what they surface. The early one is mostly about the company: is the person set up, do they have the access, the context, the introductions and the work they were promised. Most early struggle is caused by onboarding rather than capability, and that is fixable if it is found in week three rather than month three.
The later review is the honest one, and it should say plainly whether the answer is currently yes, no, or unclear. Where there are concerns, name them specifically, say what would need to change, and put the next check in the diary. Record each of these conversations at the time, briefly. If the outcome is eventually difficult, contemporaneous notes are what make the process defensible, and reconstructing them later is neither convincing nor pleasant.
Section 04
Confirm, extend or end
Confirmation should be explicit and communicated, not just an absence of action. Say so, in writing, and note the date the standard notice period begins. It costs a minute and it closes the question for both sides, which is the entire point of having a probation at all. Where the answer is yes but with something to keep working on, that belongs in the ordinary performance conversation, not in an extension.
An extension is a legitimate outcome when the evidence is genuinely inconclusive, but only with clear expectations, a support plan and a firm new end date. Without those it is a difficult conversation postponed at the employee’s expense, and a second extension almost always means the decision was made and not delivered. Ending employment during probation still requires whatever fair process applies locally, so check the rules for the country rather than assuming a shorter notice period means fewer obligations.
Section 05
Why probations lapse, and the fix
Probations lapse for a structural reason, not a human one. The end date is recorded once, at hire, in a system nobody looks at daily, and there is no moment where it presents itself to the person who has to act. Meanwhile the manager is busy and the absence of a problem feels like a decision. By the time anyone checks, the date has passed and confirmation has happened by default, which is exactly the outcome the period exists to prevent.
The fix is to make the date arrive rather than be looked up. Set it from the policy at the moment of hire so it is never blank, surface it before it is due rather than on the day, and put it in front of the manager who owns the decision. Everything else, the reviews and the criteria, only works if the calendar does its job first. A probation process that depends on someone remembering is a probation process that ends by expiry.
