Unpaid overtime in Ireland: what the law actually requires

There is no general statutory overtime premium

In the Republic of Ireland there is no automatic legal right to a fixed overtime uplift such as time and a half or double time. Higher overtime rates come from your contract, a staff handbook term, a collective agreement, or a sector Employment Regulation Order (ERO) or Sectoral Employment Order (SEO). The Organisation of Working Time Act 1997 (OTWA) sets hours, rest and leave rules. It does not invent a nationwide overtime multiplier.

That does not make extra hours free. Hours you were required or expected to work, and that were never paid, are still wages under the Payment of Wages Act 1991. Non-payment or short payment can be treated as an unlawful deduction. The certain floor is at least your normal hourly rate (or the contractual overtime rate if one exists), plus the National Minimum Wage average check. Detail: what Irish overtime rules actually require.

Contract, overtime clauses and time off in lieu

Employers must give core written terms within five days of starting work, including information about hours and pay. Check what counts as overtime and whether a higher cash rate or time off in lieu (TOIL) applies. See written terms within five days.

Some workplaces offer TOIL instead of cash. Both cash overtime and TOIL are contractual or policy choices, not a universal statutory premium. If TOIL was the deal, diary when the lieu time should have been given. TOIL that never arrives is still an unpaid-hours problem with a different label.

Sector overlays can set overtime or Sunday rates above the National Minimum Wage. Confirm the live instrument on workplacerelations.ie before you quote a figure: Employment Regulation Orders and sector rates. Sunday work under OTWA section 14 is a separate "reasonable" allowance / higher rate / paid time off rule, not a fixed percentage you can invent: Sunday work premium in Ireland.

Unpaid hours and the National Minimum Wage floor

Under the National Minimum Wage Act 2000, if someone works more hours than they are paid for, the average hourly rate must not fall below the legal minimum. From 1 January 2026, workers aged 20 and over are entitled to €14.15 an hour (S.I. 472/2025 / WRC). Age 19 is €12.74; age 18 is €11.32; under 18 is €9.91. Board and lodgings allowances also update from that date. Always re-check the live table on WRC National Minimum Wage or Citizens Information.

Extra unpaid work stretches the hour count and can drag the average under €14.15 even if the headline rate on the offer letter looked fine. Worked method: how to calculate unpaid hours and NMW underpayment in Ireland. Tips and gratuities cannot be used to top up contractual wages to the floor: Tips and Gratuities Act.

"You are salaried so overtime does not exist" is not a complete answer if unpaid extras push you below the legal floor.

Evidence that holds up

Before you argue about "overtime law", open the paperwork:

• Written terms / contract: normal hours, overtime definition, rate or TOIL.
• Payslips: do overtime hours appear when pay varies with time worked? See payslips under the Payment of Wages Act.
• Rotas, clock records, messages: proof you were asked or expected to work the extra time. Employers must keep prescribed working-time records (often Form OWT1) for at least three years. Missing records can help your case: working-time records and the WRC.
• Unpaid training or trial shifts, and unlawful till / uniform deductions, can also drag pay down: unpaid training and trial shifts, unlawful deductions from wages.

What to do next

Calculate hours beyond normal, the contractual rate or TOIL terms, and an NMW average check. Raise it in writing with your employer. If informal contact fails, a Workplace Relations Commission (WRC) complaint is the usual route for unpaid wages and many working-time issues. Roadmap: how to claim unpaid wages and WRC time limits.

Paye Mes Heures can help you estimate unpaid overtime and NMW-style shortfalls so an email to HR or a WRC complaint starts with numbers. It prepares a dossier. It does not replace the WRC, the Labour Court, legal advice, or Citizens Information, and it is not a finished Ireland WRC simulator.

Frequently asked questions

Must overtime always be paid at time and a half?

No. There is no general statutory overtime premium in Ireland. Higher rates come from the contract, a collective agreement, or a live ERO/SEO. Unpaid extra hours can still be wages at your normal rate, and they can breach National Minimum Wage.

Does a salary cancel overtime?

A salary is a payment method. It does not cancel a contractual overtime clause, and it does not cancel the NMW average check once unpaid extras count as hours.

Is the 48-hour week an overtime pay rule?

No. The 48-hour average is an OTWA limit on hours, not an automatic premium. Ireland has no UK-style individual written opt-out from that average. Details: Organisation of Working Time Act guide.

How long do I have to start a claim?

A WRC complaint is generally due within 6 months of the alleged contravention. The Adjudication Officer may extend that to 12 months where there is reasonable cause (Workplace Relations Act 2015 / WRC procedures). Protect the date early.
