Overtime and the Sunday premium in Ireland: what the law says

Overtime is one of the most searched pay questions in Ireland and one of the least regulated. There is no statutory overtime rate, no law that says extra hours must be paid at time and a half, and no automatic entitlement to be paid for them at all. What you are owed comes from three places: your contract, any order that covers your sector, and the floor set by the minimum wage and working time Acts. This guide walks through each of them, then the Sunday premium, which is the one piece of extra pay the law does require.

There is no statutory overtime rate

Start with the plain fact. Neither the Organisation of Working Time Act 1997 nor the National Minimum Wage Act 2000 sets an overtime rate. The 1997 Act limits how many hours you can be asked to work and guarantees rest; the 2000 Act sets a floor for your average hourly pay. Neither says that the 41st hour in a week is worth more than the 40th.

So when someone tells you "overtime is time and a half in Ireland", they are describing a common contractual rate, not the law. Many employers do pay time and a half, and some pay double time on Sundays or public holidays, but they do so because a contract, a collective agreement or a sector order says so.

The practical consequence is that your first stop is your written terms, not an Act.

What your contract has to say about it

Under the Terms of Employment (Information) Act 1994 as amended, your employer must give you a written statement of your terms. The core terms are due within 5 days of starting and the rest, including "overtime terms, if any", within 1 month. So the contract or statement should tell you one of three things:

• Overtime is paid, and at what rate or by what method.
• Overtime is not paid because your salary covers reasonable additional hours.
• Overtime is given as time off in lieu rather than pay.

If your statement is silent on overtime, that is itself a gap you can raise. You can ask in writing for the missing term, and a missing or incomplete statement is something the WRC can deal with. The contract checker lists what the statement must contain.

Custom and practice can also matter. Where an employer has paid overtime at a particular rate for years, the WRC may treat that as an implied term even if the written contract does not spell it out. Keep your payslips: they are the record of what was actually paid.

Sector orders: EROs and SEOs

Some sectors have legally binding minimum terms above the national floor. An Employment Regulation Order (ERO) covers sectors such as security, contract cleaning and childcare; a Sectoral Employment Order (SEO) covers construction and some related trades. These orders are made under the Industrial Relations Acts and are enforceable at the WRC in the same way as the minimum wage.

Several of them set overtime and unsocial hours rates. If you work in one of those sectors, the rate in the current order is the one that applies, and a contract cannot pay you less than it. The WRC's employment law pages link the current orders. Where an order sets a rate above your contractual rate, the order wins; where your contract is more generous, you keep the contract.

If you cannot find your sector in an order, you fall back to the contract and the general law below.

The Sunday premium

Sunday is different. The Organisation of Working Time Act 1997 says that if you work on a Sunday and that fact has not already been taken into account in setting your pay, your employer must compensate you by one or more of:

• a reasonable allowance,
• a higher rate of pay for the Sunday hours,
• paid time off, or
• a combination of those.

The Act does not fix a percentage. Where the premium is disputed, the WRC asks what a comparable employee in a similar job in the sector gets for Sunday work and uses that as the measure. In practice, Sunday premiums commonly fall somewhere between a modest allowance and time and a half, but there is no figure in the Act and this site does not invent one.

"My pay already takes Sunday into account"

This is the usual answer from an employer, and it can be right. If your contract says your hourly rate is set at a level that reflects Sunday working, or your salary was agreed on the basis of a seven-day roster, the Act is satisfied. What the WRC looks for is some evidence that Sunday was actually factored in: a clause, a higher rate than weekday colleagues, or a documented agreement. A bare assertion after the fact tends to carry less weight. If your rate is the minimum wage and you work Sundays with no allowance, the position may be harder for the employer to defend, because the minimum wage leaves nothing to "take into account".

Sundays that are also public holidays

A Sunday that is also a public holiday brings in the separate public holiday entitlement under the same Act. The two are different rights and both can apply on the same day. The public holidays guide covers the four options an employer has for a public holiday.

The 48-hour average week

Whatever your contract says about overtime, the 1997 Act caps your hours. You cannot be required to work more than an average of 48 hours a week, measured over a reference period of 4 months. The reference period is 6 months in listed sectors (security, agriculture, hospitality and others) and can be up to 12 months under a collective agreement approved by the Labour Court.

Because it is an average, a 55-hour week in one month is not a breach on its own; what matters is the total over the reference period. A pattern of 50-hour weeks for four months is. The cap applies to working time, which means the hours you are at work, at your employer's disposal and carrying out your duties. Unpaid breaks are not working time; neither is your commute.

Alongside the 48 hours sit the rest rules: 11 hours' rest in every 24 and 24 hours' rest in every 7 days, plus breaks of 15 minutes after 4.5 hours and 30 minutes after 6. Overtime that eats into those is a working time complaint even if it is paid. The working hours and breaks guide sets out each rule.

Unpaid overtime and the minimum wage check

If your contract says your salary covers extra hours, the law still gives you one check that cannot be contracted out of: the minimum wage. The National Minimum Wage Act 2000 is applied over a pay reference period of up to one month. Your gross pay for the period, divided by all the hours you worked in it, must reach the rate for your age. In 2026 that is €14.15 an hour for people aged 20 and over, €12.74 at 19, €11.32 at 18 and €9.91 under 18.

Unpaid overtime pulls that average down. A worked example:

Here the pay looks fine on 160 hours (€14.38 an hour) but falls below the minimum wage once the real hours are counted. The shortfall may be recoverable at the WRC. The minimum wage tool does this arithmetic for you.

You can also ask your employer in writing for a statement of your average hourly rate for any pay reference period in the last 12 months; it must be given within 4 weeks. That statement is often the single most useful document in an unpaid overtime complaint.

Overtime, salary and "all hours" clauses

Salaried staff often ask whether an "all hours necessary" clause means unlimited free work. It does not. Such a clause can mean no overtime pay is owed for reasonable extra hours, but it cannot lift the 48-hour average, remove the rest periods, or push your average pay below the minimum wage. It also has to be in your written terms; an employer cannot rely on a clause it never gave you.

Time off in lieu is a lawful alternative to overtime pay where the contract provides for it. Keep a note of the hours you bank, because untaken lieu time is often lost track of and hard to prove later.

Records

Your employer must keep records showing the hours you work, your rest breaks and your leave. If a working time complaint reaches the WRC and the employer has no records, the burden shifts to the employer to show it complied. That is why your own log matters: a simple diary of start and finish times, breaks and extra hours, kept at the time, is persuasive evidence. Screenshots of rosters, clock-in data and messages asking you to stay late all help.

The WRC route

There are two complaint types, and which one you tick depends on what you are claiming:

• Unpaid contractual overtime is a wages complaint under the Payment of Wages Act 1991: you were owed pay under your contract and did not get it. Each missed payment is its own contravention.
• Hours over the limit, missed rest or no Sunday premium is a complaint under the Organisation of Working Time Act 1997. The WRC can order compliance and award compensation it considers just and equitable; the awards page shows what that has looked like.
• Pay below the minimum wage is a complaint under the National Minimum Wage Act 2000, usually after the written statement request above.

All three must be made within 6 months of the contravention, extendable to 12 months only for reasonable cause. The WRC deadline checker works out the date for you. There is no fee, you can represent yourself, and the first step most people take is a written request to the employer setting out the hours and the sum.

Where this leaves you

Overtime pay comes from your contract or your sector's order, not from an Act. Sunday work must be recognised unless your pay already allows for it. Whatever the contract says, your hours cannot average more than 48 a week over 4 months, your rest is protected, and your pay divided by your real hours cannot fall below the minimum wage. Run the minimum wage tool with your actual hours, including the unpaid ones, and if the number comes out short, the next step is a written request to your employer and, if that fails, a WRC complaint within the 6 months.
