Almost every employment contract has a probation clause, and almost every employer misunderstands what it does. A probation period is a contractual arrangement. It is not a statutory concept, and it does not switch off employment law for its duration.

What probation actually gives you

Three things, roughly:

  • A shared expectation that the first few months are a mutual assessment, which makes an early conversation about fit far easier to have.
  • A shorter notice period during probation, if the contract provides for one — subject to the minimum notice in the National Employment Standards, which still applies.
  • A structure for feedback, if you use it. Check-ins at four weeks, eight weeks and before the end of probation are the most useful part of the whole arrangement and the part most often skipped.

What it does not give you

The protection people think probation provides comes from somewhere else entirely: the minimum employment period for unfair dismissal. That is twelve months for a small business employer (generally fewer than 15 employees) and six months for everyone else. It is set by the Fair Work Act, and it does not move because your contract says probation is three months.

This cuts both ways. If your contract says probation is three months but you are a small business, you have twelve months of protection from unfair dismissal claims, not three. And if you are a larger employer with a six-month probation clause, the statutory period is six months regardless of what the clause says.

What probation never protects against

This is the important part. The minimum employment period only relates to unfair dismissal. It does not affect:

  • General protections claims. Dismissing someone because they exercised a workplace right — asked about their pay, took sick leave, raised a safety concern, made a complaint — is unlawful adverse action from day one. There is no qualifying period and the potential exposure is uncapped.
  • Discrimination claims. Also from day one, under both the Fair Work Act and anti-discrimination legislation.
  • Unlawful termination and breach of contract.

So “they were still on probation” is not an answer to the question that actually matters, which is why the employment ended. A dismissal during probation that follows a week after the employee first queried their award rate is a problem no probation clause will solve.

Using probation well

The businesses that get value out of probation treat it as a management tool rather than a legal one:

  • Write down what success in the first three months looks like, and give it to the person on day one — this is what a good position description is for.
  • Hold the check-ins. Every one of them. A probation review that arrives as a surprise is a failure of the process, not a result of it.
  • If it is not working, say so early and clearly, and document the conversation.
  • If you extend probation, do it in writing before the original period ends, with a clear reason and clear expectations.
  • When you do end employment during probation, give the notice the contract and the NES require, and be able to state a genuine, lawful reason.

Handled that way, probation does its real job: it makes an honest conversation about fit normal rather than confrontational. Handled as a legal shield, it provides a good deal less cover than most employers assume. If you are unsure whether a particular early exit is safe, that is a question worth asking before the conversation rather than after it.
