Ms Catherine Fahy:

The monthly allowance is an early-late allowance, which is paid to staff who work into the evening. It is a long established allowance and the grades of staff who get it are comparatively low paid. We also pay an allowance to security staff who are on call at night if anything happens during the night. If there is any type of flood or if any of the alarms are activated, the staff are on call and have to come in.
