Mr. Brian Purcell:

There were substantial issues in regard to changes in rosters and so on. As I said, additional hours and those types of arrangements are very effective over time in terms of dealing with the peaks and troughs of demand in particular areas. Simply appointing additional staff will not necessarily provide the flexibility necessary to respond to an institution's particular needs. In a 24-7 operation, one will never get to a point where service delivery is covered simply by having staff employed on a basic level of provision.
