Thank you, Mr. Chair. In general, because it takes 5.5 PYs to fill one position on a 24/7 operation, what we are talking about is generally one. If there had been in the past, two casuals called in per shift on average, now we are talking about having only one called in on average. I'm afraid I don't know what the average has been or how many are called in on a regular basis, so I don't know what the impact is going to be. But it would certainly be something that we could find out from historical data and ask the warden to advise the casual contingent what the likely impact is going to be.
As Mr. Roland pointed out, with casuals, there is not ever a guarantee of a long-term position, so we don't have the same sort of provisions as we have for full-time staff in terms of layoff.
