On-call and standby in Ireland : calculate what you are owed

• Under OTWA section 2, working time is time when you are at your place of work or at your employer's disposal, and carrying on or performing the activities or duties of your work. Any other time is a rest period.
• Being contactable at home is not automatically working time. Being required to remain at the workplace (or a place the employer fixes) and available for work is much more likely to be working time.
• Actual call-out work is ordinarily working time. If it interrupts your 11-hour daily rest, compensatory rest rules may apply.
• OTWA does not set a statutory standby hourly rate. Pay usually comes from contract, ERO/SEO, or custom. The National Minimum Wage (NMW) still floors average hourly pay for hours that count under the NMW Act.
• OTWA section 18 (zero-hours / minimum payment in certain cases) expressly says being on call for emergencies is not the same as the "make yourself available" pattern that section addresses.
• Raise shortfalls in writing. If unresolved, consider a WRC complaint within the usual time limits.

Irish rules ask two questions:

1. Is this period working time under the OTWA (rest and the average 48-hour week)?
2. What does my contract or sector instrument say I am paid, and do reckonable hours meet the NMW?

A period can be working time for rest without a special overtime rate. A retainer can be paid under contract even if quiet home standby is treated as rest for OTWA purposes.

OTWA definition (section 2)

Working time means any time that the employee is (a) at his or her place of work or at his or her employer's disposal, and (b) carrying on or performing the activities or duties of his or her work. Rest period means any time that is not working time.

Both limbs matter. Rota labels ("standby", "sleepover", "on-call") do not rewrite the statute. What you must do, where you must be, and how free you are to manage your own time do.

OTWA s.2: irishstatutebook.ie

Irish practice draws a constraint line, not a slogan.

Usually closer to working time

• You must remain at the workplace (or another place the employer determines) and be available to work.
• You cannot leave freely, or permission is rarely given.
• Sleeping on site still means presence under the employer's control for the duties of the role.
• Response expectations leave little real freedom to plan personal activities.

Where presence at a fixed workplace is required for the whole period, treating that whole period as rest is hard to square with section 2. Quiet minutes do not automatically convert presence into a rest period.

Usually closer to rest (with caveats)

• You are at home or free to choose your location.
• Your main duty is to remain contactable.
• You can organise personal and social activities in a meaningful way.
• Response and location rules do not objectively and very significantly restrict how you manage your time.

Even then, every call-out is ordinarily working time.

Grey zone: very tight home constraints

Home location alone does not settle the question. If you must stay within minutes of site, keep equipment ready, and cancel ordinary plans because response rules leave almost no freedom, an adjudicator may look harder at whether the period is still genuine rest. Irish assessment is fact-sensitive. This article does not invent a percentage threshold or import foreign case tables as Irish statute. Write down response times, location rules, call frequency, and what you can (and cannot) do while waiting.

For most employees, WRC and Citizens Information summarise:

• Daily rest of 11 consecutive hours in each 24-hour period
• Weekly rest of 24 consecutive hours in each seven days (after daily rest)
• Breaks of 15 minutes after more than 4.5 hours, and 30 minutes after more than 6 hours (payment for breaks is not a statutory entitlement)

A call-out that cuts into the 11-hour daily rest can leave you short. Where an exemption, emergency, shift change, or other permitted variation applies, the employer must usually provide equivalent compensatory rest, or, where objectively impossible under section 6(2), appropriate protection. Monetary compensation is not "appropriate protection" under the Act.

The WRC Code of Practice on Compensatory Rest Periods (S.I. No. 44/1998) includes an "on call" maintenance call-out example. If no exemption applies, the employee is entitled to the full 11 consecutive hours' rest from the end of the call-out. Compensatory rest for missed daily rest should generally be given as soon as possible, typically in an adjacent timeframe. Some sectors have General Exemptions (S.I. No. 21/1998) from sections 11 to 13, with equivalent rest still required. Check whether your role is covered.

Code of Practice: workplacerelations.ie

OTWA regulates organisation of time. It does not create a universal Irish standby tariff. Check, in order: (1) your contract and statement of terms; (2) any ERO, SEO, registered employment agreement, or collective agreement; (3) whether hours that count as working hours for NMW purposes leave your average hourly pay below the National Minimum Wage.

Overtime and standby rates are largely contractual or sector-instrument territory. A quiet home period treated as rest for OTWA may still attract a contractual retainer. Hours of actual work must not drag the NMW average under the legal floor.

Section 18 is not a standby pay formula

OTWA section 18 deals with certain zero-hours and low-hours availability patterns. Section 18(7) states that references to making yourself available are not to be read as including being on call for emergencies that may or may not occur. Do not treat the section 18 minimum-payment arithmetic as a ready-made standby wage. Genuine on-call still sits inside the OTWA working-time and rest framework above.

A. Staff quarters, Cork. Campus presence from 22:00 to 07:00 with a duty to respond: typically working time for OTWA. Pay still depends on contract or sector rules.

B. Phone at home, Dublin. Contactable after a day shift, free to leave the house: quiet waiting is more likely rest. Each call-out is working time. Ask about compensatory rest if the 11-hour rest is broken.

C. Tight radius, Limerick. Home location but must reach site within a few minutes: high constraint, fact-sensitive. Document the rules. Do not rely on a UK blog figure.

D. Retained firefighter-type pattern. Often sits in special exemption frameworks. Read the specific regulations and local agreement.

Employers must keep working-time records under OTWA section 25 and S.I. No. 473/2001. Keep your own file: contract and on-call policy; rotas; same-day diary of calls; texts ordering standby; payslips; notes of missed 11-hour rests.

Raise the issue internally first. Separate (i) whether quiet standby is working time, (ii) whether call-outs were recorded and paid, and (iii) whether compensatory rest was given. Ask for the working-time records for the weeks in dispute.

If unresolved, complain to the Workplace Relations Commission. Time limits commonly run about 6 months from the alleged contravention, with a possible further 6 months where reasonable cause is shown. Do not bank on the extension. Appeals typically go to the Labour Court.

WRC: workplacerelations.ie

1. "On-call means unpaid by definition." Quiet home contactability may be rest for OTWA, but call-out work is still work, and contracts often pay retainers.
2. "I slept, so it cannot be working time." Sleeping on site under a duty to remain and respond is not free rest at home.
3. "A UK case says X percent, so Ireland matches." Use the OTWA text, WRC and Citizens Information materials, and Irish dispute routes.
4. "OTWA working time automatically equals overtime rates." Time and rest are one regime. Pay rates are usually contract or ERO/SEO territory, with the NMW floor underneath.
5. "Section 18 minimum payment covers my standby week." Section 18(7) carves genuine on-call emergencies out of that pattern.
6. "We paid cash instead of rest." Compensatory rest (or appropriate protection) is not a cash substitute under section 6.
7. "No diary, so nothing happened." Same-day notes and employer records matter.

If your month mixes day shifts, home standby, and unpredictable call-outs, the arithmetic gets messy. Paye Mes Heures (payemesheures.fr) helps workers organise dates, hours, and amounts before they write to an employer or prepare a WRC file. Use it as a preparation aid under the Irish rules that apply to you and under your contract.

It is not Irish legal advice and not a finished Ireland-only calculator. Your contract, any ERO or SEO, Citizens Information, the OTWA, the Compensatory Rest Code of Practice, and the WRC remain the anchors. For high-constraint or residential roles, speak to a union or adviser as well.
