Mr. Barry O'Brien:

Part of the conditions of a theatre nurse in one of the major hospitals is that he or she would be available for an out-of-hours service. We pay an on-call allowance for that. It goes with the territory. I do not wish to complicate this for the Deputy, but there is on-call, on-call with stand-by and on-call being present on-site. All of these complications come into it.
