For each ‘relevant person’, carer's leave may be taken in a continuous period of 104 weeks, or in a number of separate periods, not exceeding 104 weeks in total.
Your employer has the right to refuse to grant carer's leave for a period of less than 13 weeks, 'on reasonable grounds'. However, your employer must specify in writing to you the grounds for their refusal. If you are not satisfied with their reasons, you have the right to appeal to the Adjudication Service of the Workplace Relations Commission (WRC).
If the leave is taken in separate periods, there must be a gap of at least 6 weeks between the periods of leave. for a particular ‘relevant person’.
The Act does, however, allow for employer and employee to agree more favourable terms to the employee than those provided for under the Act.
