Working time and rest breaks in Ireland
Reviewed by Mellow Editorial Team, HR & payroll content team
Working time rules in Ireland are set out in the Organisation of Working Time Act 1997. The law sets limits on weekly working hours, requires minimum rest periods between shifts, and gives workers the right to paid breaks during the working day. Employers who ignore these rules face complaints to the Workplace Relations Commission (WRC) and potential awards against them.
The 48-hour weekly limit
The maximum average working week is 48 hours. This is calculated as an average over a reference period — typically four months, though this can extend to six months in some sectors, or up to 12 months under a collective agreement. It is an average, not a hard weekly cap, so a busy period with longer hours can be balanced against quieter weeks.
Zero-hour and variable-hours workers are covered by the same limit. Senior managers and some genuinely autonomous workers can be exempt, but this is a narrow category. If your employees are doing defined work within set hours, assume the 48-hour limit applies.
Keep records of hours worked. Revenue and the WRC can both request them, and the burden of proof in a dispute typically falls on the employer.
Daily and weekly rest requirements
Every employee is entitled to:
- 11 consecutive hours of rest in every 24-hour period
- 24 consecutive hours of rest in every seven days (or 48 hours in every 14 days)
These are minimum entitlements. In practice, a standard working pattern of five days on, two days off will satisfy the weekly rest requirement comfortably. The daily rest rule is the one that catches employers out — particularly in hospitality, healthcare, retail and logistics, where split shifts or late-finish/early-start patterns can eat into the 11-hour gap.
If your business needs to depart from the standard rest intervals — for example, due to seasonal demand or continuity of service — there are provisions for "compensatory rest". This means the missed rest is given back within a reasonable period. It does not mean rest can simply be waived.
Break entitlements during the working day
Employees are entitled to a 15-minute break after working more than 4.5 hours, and a 30-minute break after working more than 6 hours (which can include the first 15-minute break).
The Act does not require these breaks to be paid — that is a matter for the contract of employment or any applicable sectoral employment order. Many employers do pay for shorter breaks as a matter of policy, but the statute is silent on pay.
Breaks must be taken away from the employee's workstation. An employee asked to remain available or to monitor something during their break is not, in practice, getting a proper break.
Night workers
Night work has specific protections. A night worker should not work more than an average of eight hours in each 24-hour period over the relevant reference period. They are also entitled to a health assessment before taking up night work, and on a regular basis thereafter. If a health problem is connected to night work, you must transfer the employee to day work where possible.
Night work is broadly defined as work between midnight and 7am. If a significant portion of an employee's working time falls in this window regularly, they likely qualify as a night worker.
Keeping records
The Organisation of Working Time Act requires employers to keep detailed records of hours worked, including start times, finish times and breaks taken. These must be retained for at least three years and made available to a WRC inspector on request.
Many payroll and workforce management systems can capture this data automatically. If you are still relying on paper timesheets or informal tracking, that is worth addressing — not just for compliance, but because accurate time records also underpin correct payroll calculations, holiday pay, and how Mellow runs payroll across six countries.
Annual leave and its interaction with working time
Annual leave entitlement is a minimum of four working weeks per year for a full-time employee. The precise calculation depends on working pattern — for employees with irregular hours, the entitlement can be calculated as 8% of hours worked in the leave year, subject to the four-week maximum.
A point that frequently causes confusion: public holidays are separate from annual leave. An employee is entitled to benefit from public holidays on top of their annual leave, not as part of it.
Where an employee is absent due to illness during a period of annual leave, current case law and WRC decisions generally support their right to take the leave at a later date. This aligns Ireland with broader EU working time jurisprudence.
