Hours of Work
The Organisation and Working Time Act 1997 states that the maximum average working week for many employees cannot exceed 48 hours. This does not mean that a working week can never exceed 48 hours, it is the average that is important.
The average may be calculated in one of the following ways:
- over 4 months for most employees
- over 6 months for employees working in the security industry, hospitals, prisons, gas/electricity, airport/docks, agriculture and employees in businesses which have peak periods at certain times of the year such as tourism.
- over 12 months where there has been an agreement between the employer and the employees to this effect which has been approved by the Labour Court.
The calculation of 48 hours does not include annual leave, sick leave or maternity/adoptive/parental leave.
The legislation also lays down rules for night workers, minimum breaks and rest periods. There are also special provisions in relation to Sunday working (see below).
Sunday working
If you do Sunday work your entitlement to extra pay may be agreed between you and your employer. Under the Organisation of Working Time Act, if there is no agreement about your pay, your employer must give you one or more of the following for Sunday working:
- a reasonable allowance;
- a reasonable pay increase; or
- reasonable paid time off work
What is reasonable depends on all the circumstances. It is a matter for negotiation between you and your employer and, where applicable, your trade union. Some guidance may be obtained by referring, where possible, to agreements applying to comparable employees elsewhere in similar employments. Under the Organisation of Working Time (Records) (Prescribed Form and Exemptions) Regulations 2001, your employer is required to keep detailed records of your working hours.
Overtime
Overtime is work done outside normal working hours. There is no statutory obligation on employers in Ireland to pay employees higher rates – for example, double time – for work completed in overtime. You must, however, receive at the very least your normal hourly rate of pay for overtime.
How to apply
Disputes under the Organisation of Working Time Act 1997 should be referred to a Rights Commissioner . You should make a complaint within 6 months of the dispute occurring. However, a Rights Commissioner may extend this time limit for up to 12 months if there was reasonable cause for not bringing the complaint within the first 6 months.
Further information on working hours and your employment rights is available from the Information Services of the National Employment Rights Authority.
