First of all, in order to qualify for public holiday entitlement you must have worked at least 40 hours in the five weeks ending on the day before the public holiday. (Please refer to the INMO's explanatory leaflet, Public Holiday Entitlements).
Nurses/midwives employed in the public health service who work a ‘5 over 7’ roster (7-day week) receive additional annual leave in lieu of their liability to work on public holidays, i.e. 10 days in the case of full-time nurses/midwives and proportionately less in respect of job-sharers and part-timers. In addition, they also receive double pay in respect of any public holiday on which they are required to work.
Job-sharing nurses/midwives who work Monday to Friday and who do not normally work on the day on which the public holiday falls are entitled to one-tenth of their normal fortnightly pay for the public holiday.
Part-time nurses/midwives who work Monday to Friday and who do not normally work on the day on which the public holidays falls are entitled to one-fifth of their normal weekly pay for the public holiday.
