Probation periods used to be whatever an employer wrote into the contract — three months, six months, a year, with no statutory ceiling at all. That changed on 1 August 2022. Irish employers now face a hard statutory cap on how long a probationary period can run, and getting it wrong in a contract or a dismissal can expose a claim that didn't exist before the rule changed.
How Long Can a Probation Period Last in Ireland?
Under the European Union (Transparent and Predictable Working Conditions) Regulations 2022 (S.I. No. 686 of 2022), a probationary period for a private sector employee cannot exceed 6 months. This applies regardless of what an employment contract says — a contract clause providing for a longer standard probation simply isn't enforceable.
Public sector probationary periods are treated differently and can run for up to 12 months from the outset.
Can a Probation Period Be Extended Beyond 6 Months?
Yes, but the bar is specific. An extension is only permitted:
- on an exceptional basis — extending should be the exception in your organisation, not a routine next step after every initial probation, and
- where it is genuinely in the interest of the employee — for example, giving someone more time to improve rather than dismissing them, or because they were absent on protected leave during the original period.
Even with a valid exceptional reason, the total probationary period — original plus extension — cannot exceed 12 months. Most employment law commentators advise capping any extension well short of that ceiling in practice, since notice periods count toward an employee's overall service, and an employer can inadvertently let someone accrue the 12 months' continuous service needed for unfair dismissal protection before the dismissal actually takes effect.
If an employee is absent on statutory leave — sick leave, maternity, paternity, parent's or adoptive leave — during their probation, the probationary period is automatically extended by the length of that absence. Time spent on protected leave doesn't count toward the 6-month clock.
What About Fixed-Term Contracts?
The 6-month rule doesn't apply in the same way to fixed-term contracts. Instead, under the Protection of Employees (Fixed-Term Work) Act 2003 as amended, any probationary period must be proportionate to the expected duration of the contract and the nature of the work — a 6-month probation on a 12-month fixed-term contract is unlikely to hold up as proportionate. If a fixed-term contract is renewed for the same role and tasks, the renewed contract cannot carry a new probationary period.
What Rights Do Employees Have During Probation?
Being on probation doesn't put an employee outside the law. From day one, probationary employees are entitled to:
- the national minimum wage
- working time and rest break protections under the Organisation of Working Time Act 1997
- statutory annual leave (accrued at the normal rate)
- public holiday entitlements
- protection from discriminatory dismissal on any of the protected grounds (gender, age, race, religion, disability, family status, and others)
The major practical difference is unfair dismissal protection under the Unfair Dismissals Acts 1977–2015, which generally only applies once an employee has 12 months of continuous service. This is the main reason probation exists as a concept in Irish employment law at all — it gives an employer a window to end the relationship with comparatively less procedural exposure, provided the reason for dismissal isn't discriminatory and isn't tied to a protected right.
Even so, dismissing during probation isn't risk-free. Irish courts have indicated that some level of fair procedure is still expected, particularly for dismissals related to conduct rather than simple unsuitability for the role. Documenting performance concerns and giving an employee a genuine opportunity to respond remains good practice during probation, not just after it.
What Should a Probation Clause Actually Say?
A compliant probation clause should set out, in writing, before or on the employee's start date:
- the length of the probationary period (within the statutory cap)
- the criteria the employee will be assessed against
- the employer's right to extend at its discretion, and on what basis
- the notice period that applies specifically during probation, if shorter than the standard contractual notice
This information about the probationary period now also needs to be included in the Day 5 statement of core terms required under the Employment (Miscellaneous Provisions) Act 2018, as amended by the 2022 Regulations — it's no longer something that can wait for the full written statement of terms.
