Probation Periods in Ireland Do Not Protect Employers as Much as You Think

Most Irish employers assume that a probation period in Ireland gives them a clean exit route if a new hire does not work out. The thinking goes: “They are on probation, so we can let them go without any risk.” This belief is widespread, and it is wrong. The Workplace Relations Commission (WRC) has repeatedly found against employers who dismissed employees during probation without following a fair process. Getting probation wrong does not just cost time; it costs money.

Quick Answer: Probation Periods in Ireland for Employers

A probation period does not suspend an employee’s rights. Employers in Ireland must still follow fair procedures, provide written reasons for ending probation, and comply with statutory notice requirements. Failing to manage probation correctly exposes employers to WRC claims for unfair dismissal, payment of wages breaches, and more.

Mistake 1: Assuming Probation Means You Can Dismiss Without Process

This is the single most common mistake we see at PurpleTree HR. An employer hires someone, includes a six-month probation clause in the contract, and then assumes they can simply end the employment at any point during that window with no procedure at all.

The reality is more complicated. While the Unfair Dismissals Acts 1977-2015 generally exclude employees with less than 12 months’ continuous service from bringing unfair dismissal claims, this does not mean employers are free from scrutiny. Employees on probation can still bring claims under other legislation, including the Industrial Relations Acts, the Employment Equality Acts, and the Payment of Wages Act 1991.

The WRC has consistently held that natural justice applies regardless of service length. That means an employee on probation is still entitled to be told what the concern is, given a chance to respond, and treated fairly. Skipping this process is where employers get caught.

Mistake 2: Setting a Probation Period That Exceeds the Legal Maximum

Since the European Union (Transparent and Predictable Working Conditions) Regulations 2022 took effect in December 2022, private sector probation periods are capped at six months. An employer can extend probation beyond six months only in exceptional circumstances, and even then only where the extension is in the employee’s interest. The total cannot exceed 12 months.

We regularly review employment contracts for clients through our strategic HR consulting service and still find probation clauses written before 2022 that specify nine or even twelve months as standard. These outdated terms create an immediate compliance risk. If a dispute arises, the WRC will look at the contract and note the non-compliant clause, which undermines the employer’s credibility from the outset.

Public sector employees have a different ceiling of 12 months, but for the vast majority of SMEs, six months is the line.

Mistake 3: Failing to Conduct Probation Reviews

A probation period only works if it is actively managed. Too many employers treat it as a passive waiting period: hire the person, leave them to it for five months, then panic when things are not working out.

The WRC expects to see evidence that the employer engaged with the employee during probation. That means documented check-ins, clear feedback on what is going well and what needs to improve, and a genuine opportunity for the employee to meet expectations. Without this trail, an employer who dismisses at the end of probation looks like they made an arbitrary decision rather than a considered one.

This is one of the areas where we add the most value for our clients. Through our HR Essentials service, we build probation review frameworks that create the right documentation at the right intervals, so employers are protected if things do not work out.

Mistake 4: Forgetting That Statutory Rights Apply from Day One

An employee on probation still accrues annual leave from day one under the Organisation of Working Time Act 1997. They are entitled to statutory notice (one week after 13 weeks of service) under the Minimum Notice and Terms of Employment Acts 1973-2005. They are protected against discrimination under the Employment Equality Acts from their first day.

A situation we see frequently is an employer who lets someone go during probation and pays no notice because “they were only on probation.” If that employee has passed 13 weeks of service, they are owed at least one week’s notice, or payment in lieu. Overlooking this creates a straightforward Payment of Wages claim at the WRC.

Similarly, since the Sick Leave Act 2022 took effect, statutory sick pay entitlements apply based on service and qualifying criteria. Probation does not create an exemption.

Mistake 5: No Written Probation Terms in the Contract

Some employers mention probation verbally during the interview or onboarding process but fail to include it in the written contract of employment. Without a written clause, the employer has no contractual basis for the probation period, and the protections they think they have simply do not exist.

Since the Employment (Miscellaneous Provisions) Act 2018 amended the Terms of Employment (Information) Acts, employers must provide written terms within five days of commencement. Those terms should include the duration and conditions of any probation, which the Transparent and Predictable Working Conditions Regulations 2022 added to the day-five statement. If an employer then tries to dismiss someone “on probation” but cannot point to a contract that establishes the probation, the WRC will take a dim view.

When we guide clients through onboarding, contract drafting is one of the first things we address. A well-drafted probation clause sets the foundation for everything that follows. Our compliant contracts of employment build the probation clause in correctly from day one, so the protection you think you have actually exists.

Mistake 6: Extending Probation Without a Valid Reason

Some employers extend probation automatically as a precaution, without any documented reason. This is risky. The 2022 Regulations allow extension only in “exceptional circumstances” and only where the extension is objectively justified and in the employee’s interest (for example, where the employee was on extended leave during the initial period and did not get a full opportunity to demonstrate their capability).

A blanket extension because the employer “has not had time to assess” the employee, or because it is “company policy” to extend everyone, does not meet this threshold. If challenged, the employer would need to show why the specific circumstances were exceptional.

In our experience advising employers across Ireland, this is an area where getting the paperwork right matters enormously. A one-paragraph letter confirming the extension with reasons is the difference between a defensible position and a vulnerable one. Our employment advice team handles these communications for clients regularly.

Mistake 7: Dismissing for Performance Without Addressing Conduct Properly

There is an important distinction between ending probation due to capability (the employee cannot do the job to the required standard despite support) and ending it due to conduct (the employee did something wrong). Employers often blur the two, and this causes problems.

If the reason for dismissal is actually a conduct issue, the WRC will look for evidence of a disciplinary process, even during probation. SI 146/2000, the Code of Practice on Grievance and Disciplinary Procedures, applies to all employees. A conduct-related dismissal during probation that bypasses any investigation or hearing is exactly the type of case that generates a successful WRC claim under the Industrial Relations Acts.

When our clients face this situation, we help them distinguish between a probation review (performance-focused) and a disciplinary process (conduct-focused), and we manage whichever procedure applies.

The Real Cost of Getting Probation Wrong

Employers who mishandle probation face more than just WRC claims. There is the cost of recruiting a replacement, the disruption to teams, and the reputational risk of being named in a WRC decision. Crucially, there is no minimum-service threshold for an Employment Equality claim, so even a short-service employee carries full exposure. A successful Employment Equality claim is enforceable and capped at the greater of two years’ remuneration or €40,000 (€13,000 for a person who is not an employee, such as a job applicant). A complaint under the Industrial Relations Acts produces a non-binding WRC recommendation rather than an enforceable award, but a finding against the employer still adds to the cost and disruption.

Beyond the financial risk, there is the time cost. A WRC complaint means gathering documentation, preparing submissions, and attending hearings. For SME owners and managers, that is time taken away from running the business. Having the right processes in place from the start avoids this entirely.
