Unfair Dismissal in Ireland: The Complete Guide

Unfair dismissal in Ireland is governed by the Unfair Dismissals Acts 1977-2015, and the Acts are built around one idea that changes everything: the employer, not the employee, has to justify the dismissal. This guide walks the whole claim from the day you are told to the day the WRC decides, in the order the questions actually arise.

1. The Presumption: Section 6(1)

Section 6(1) provides that a dismissal is deemed to be unfair unless, having regard to all the circumstances, there were substantial grounds justifying it. That is the whole architecture of unfair dismissal Ireland in one sentence. The employee proves three things: that there was a dismissal, that the Acts apply, and that the complaint is in time. Everything else — the reason, the fairness of the reason, the fairness of the process, the proportionality of the sanction — is for the employer to prove. An employer that turns up to the WRC with a reason but no evidence of how the decision was reached is on the wrong side of the presumption from the first minute.

2. The Fair Grounds: Section 6(4)

An employer can justify a dismissal only by reference to the grounds in section 6(4):

• Capability, competence or qualifications for the work the employee was employed to do — the ground behind sick leave, performance and probation dismissals;
• Conduct — from a pattern of minor breaches to a single act of gross misconduct;
• Redundancy — the job, not the person, is going (our sister site at redundancysolicitors.ie covers redundancy in depth);
• Contravention of statute — continuing the employment would break the law, for example a lost licence that the job requires.

The ground must be the real reason. An employer that dresses a personality clash as poor performance, or a cost cut as misconduct, fails at this step whatever process it ran afterwards.

3. The Fair Procedure: S.I. 146/2000

A fair ground does not save an unfair process. The Code of Practice on Grievance and Disciplinary Procedures (S.I. 146/2000) sets the standard: the allegation put in writing, an investigation into the facts, a hearing at which the employee can respond with a representative present, a decision that is proportionate to what was found, and a right of appeal. The employer must also apply its own procedures, because a handbook promise is a contractual promise. In practice, more unfair dismissal claims are won on procedure than on substance: the manager who investigated and then decided, the hearing held before the evidence was shared, the appeal that went to the person who made the original decision. The employee can ask for a written statement of the reasons for dismissal, due within 14 days under section 14(4), and that request should be the first letter sent after any dismissal.

4. Who the Acts Cover: One Year, and the Exceptions

Section 2(1)(a) requires one year’s continuous service. Section 6(2A) removes that requirement where the dismissal results from pregnancy, giving birth, breastfeeding or related matters; from availing of maternity, adoptive, paternity, parental, carer’s, parent’s or force majeure leave; from trade union membership or activity; from a protected disclosure; or from exercising rights under the National Minimum Wage Act. Section 3 separately excludes a dismissal during a written probation or training period of one year or less, again subject to those exceptions. Anyone inside the first year who does not fit an exception is not without a route: section 20(1) of the Industrial Relations Act 1969 allows a referral to the Labour Court for a non-binding recommendation, the Employment Equality Acts 1998-2015 have no service requirement for a discriminatory dismissal, and a notice claim is available after 13 weeks. The options are set out in dismissed with less than 12 months’ service.

5. The Time Limit: Six Months From the Date of Dismissal

A complaint must be lodged with the WRC within six months of the date of dismissal, extendable to twelve months only where reasonable cause prevented an earlier complaint (section 8(2)). The date of dismissal is a legal date, not a calendar one: under section 1 it is the date notice expired or, where no proper notice was given, the date on which proper contractual or statutory notice would have expired. Statutory notice under the Minimum Notice and Terms of Employment Acts 1973-2005 runs from one week after 13 weeks’ service to eight weeks after fifteen years, so an employee dismissed on the spot often has a later date of dismissal than they think. Employers argue the opposite, so the safe course is to lodge within six months of the day you were told. The WRC Deadline Calculator works your dates through.

6. Redress: Section 7

If the dismissal is found unfair, the WRC orders one of three things. Reinstatement returns the employee to the same job as if never dismissed, with back pay. Re-engagement returns the employee to a comparable role on terms the WRC sets. Compensation is for financial loss attributable to the dismissal, up to 104 weeks’ remuneration, or up to four weeks’ remuneration where there is no financial loss; for a protected disclosure dismissal the cap is 260 weeks. There is no compensation for stress or injury to feelings, and the employee must mitigate loss by seeking work. Compensation is the usual order, and because it is measured by loss rather than by unfairness, two identical dismissals can produce very different results. The arithmetic is in how unfair dismissal compensation is calculated.

7. The WRC Process in Brief

The complaint goes in through the WRC eComplaint portal. Mediation is offered first: free, voluntary and confidential, with 1,034 mediations in 2025 and 54% resolved. If the claim proceeds, written submissions are due 15 working days before the hearing, the hearing is public and the parties are named in the decision unless special circumstances exist, evidence may be taken on oath, and remote hearings are available unless the interests of justice require otherwise. The WRC does not award legal costs. Either side may appeal to the Labour Court within 42 days of the decision; an unappealed decision must be carried out within 56 days, after which the District Court can enforce it. The practice page on unfair dismissal claims covers what the firm does at each stage.

8. What to Do This Week

• Write down the date you were told and the notice, if any, you were given;
• Request the written reasons for dismissal under section 14(4);
• Gather the contract, the handbook, the dismissal letter and every disciplinary document;
• Start the job search and keep every application and reply — mitigation is measured from day one;
• Do not sign an exit document without advice;
• Take advice while the internal appeal is running, not after — the appeal does not pause the clock.
