What is a probation period?
A probation period, called a trial clause in Belgian employment law, is an agreed opening phase of a contract during which either side can end the relationship more easily and more quickly than afterwards.
The reason it matters in Belgium is mostly historical. For the majority of employment contracts, it no longer exists.
Does Belgium still have a probation period?
Not for most contracts. The trial clause was abolished for ordinary employment contracts from the start of 2014, when the single employment status came in, and a clause of that kind written into a standard contract today has no effect.
It survives in two arrangements: student contracts, and contracts governed by the law on temporary and agency work. There the first three days actually worked count as a trial period, during which either side can end the contract without notice or compensation, and in a student contract it applies automatically whether or not the contract mentions it, as the SPF Emploi guidance on the trial period sets out.
Outside those cases, an employer asking you to sign a probation clause is either using an outdated template or describing something else.
What replaced the probation period?
The notice period calculation itself. Because Belgian notice is built from seniority, it is very short on both sides during the first months of a contract and grows from there. The early flexibility a trial clause used to provide is now produced by the statutory scale, without a clause.
The practical difference is that this flexibility is symmetrical and automatic. It applies whether or not anyone thought about it when the contract was drafted.
What should you look for instead in a new contract?
Since there is no trial phase to negotiate, the terms worth reading closely are the ones that will still apply in a year: function and how it can be changed, pay and how it is reviewed, working time, and any non-compete clause.
If the engagement is genuinely meant to be a trial before a permanent hire, that is a different structure with a different name. See contract to perm, which Sparagus labels explicitly on the roles currently open.
