Irish Employment Law

How Annual Leave is Calculated in Ireland

Annual leave entitlement in Ireland is governed by the Organisation of Working Time Act 1997. Under the Act, every employee is entitled to whichever of the following three methods gives them the most annual leave:

1

Four working weeks per leave year

An employee is entitled to 4 working weeks if they work at least 1,365 hours in the leave year. For a standard full-time employee working 39 hours/week for the full year (2,028 hours total), this is the method that applies and equals 20 days.

2

One-third of a working week per qualifying month

An employee earns 1/3 of a working week for each calendar month in which they work at least 117 hours. This method is useful for employees who are only employed for part of the year.

Example: 8 qualifying months x 1/3 week = 2.67 weeks of leave
3

8% of total hours worked (capped at 4 weeks)

The employee is entitled to 8% of the total hours they work in the leave year, subject to a maximum of 4 working weeks. This method is most commonly used for part-time and casual workers with variable or low hours.

Example: 900 hours worked x 8% = 72 hours annual leave
Important: The employer must use whichever of the three methods gives the employee the greatest entitlement. An employer cannot choose the method that results in less leave for the employee.

Annual Leave for Part-Time Workers in Ireland

Part-time employees have the same rights to annual leave as full-time employees, calculated on a pro-rata basis. In practice, the 8% method is most commonly used for part-time workers, as it automatically adjusts for the hours they actually work. For example, a part-time employee working 20 hours per week for a full year is entitled to 83.2 hours of annual leave (20 hrs x 52 weeks x 8%).

When Must Annual Leave Be Taken?

Annual leave must generally be taken within the leave year it accrues, or within 6 months of the end of that leave year where the employer and employee agree. Employees who were unable to take their annual leave due to illness may carry it over for up to 15 months after the end of the relevant leave year, following a 2015 amendment to the Act.

What is the minimum annual leave entitlement in Ireland?

Under the Organisation of Working Time Act 1997, every employee is entitled to a minimum of 4 working weeks of paid annual leave per year. For a standard full-time employee (5 days a week), this equals 20 days. This is separate from public holidays, of which there are 10 per year.

How is annual leave calculated for part-time workers in Ireland?

Part-time employees are entitled to annual leave calculated as 8% of the total hours they actually work in a leave year, subject to a maximum of 4 working weeks. For example, a part-time employee working 20 hours per week for a full year is entitled to 83.2 hours of annual leave (20 x 52 x 8%).

Do public holidays count as annual leave in Ireland?

No. Public holidays are entirely separate from annual leave in Ireland. Employees are entitled to both their 4 weeks of annual leave and all 10 public holidays. An employer cannot count public holidays as annual leave days.

Can annual leave be carried over to the next year in Ireland?

Annual leave must generally be taken within the leave year it is accrued, or within 6 months of the end of that leave year by agreement. However, employees who could not take annual leave due to illness may carry it over for up to 15 months after the end of the relevant leave year.

What happens to unused annual leave when an employee leaves their job?

On termination of employment, an employee is entitled to be paid for any accrued but untaken annual leave. This payment must be made on the date the employment ends. Failure to pay for unused annual leave on termination is a breach of the Act and can be brought as a complaint to the WRC.

Do employees accrue annual leave while on sick leave in Ireland?

Yes. Following an amendment to the Organisation of Working Time Act 1997, employees in Ireland continue to accrue annual leave entitlement while on certified sick leave, regardless of the length of the absence.
