The Department of Public Expenditure and Reform prepared an FAQ document in relation to 'working arrangements and leave associated with COVID-19'. The contents of this document apply to all those employed in the Civil and Public Services, including all public health sector employees.
A copy of this document is available to view at this website, and section 3.1 sets out the position in relation to leave and pay for those who are absent from work due to Covid-19.
The quick guide on Page 37 may be of particular interest (scenarios 7).
