Thank you very much. This is an area that I have asked my officials to focus on. It's difficult to do it, because, as you can imagine, in terms of retention, if you have 1,000 people off sick with COVID, what are you going to do to fill those vacancies? How are you going to take the pressure off those people who have to make up for that sick leave? And if we don't use agency nurses, then the pressures are going to be even greater. Now, I'm very unhappy in terms of how much we spend on agency staff at the moment, and that's why I've asked HEIW to focus on this work and to ensure that we work with the unions, quickly, to ensure that we're in a better position. But, at the end of the day, what's needed is to convince more nurses to remain and to continue with training provision. But I have to say that the staffing levels in Hywel Dda are now at unprecedented levels. Eleven thousand people work for the health board, and, in terms of nurses, there are 136 more than there were three years ago. So, there are more staff. But the demand is increasing constantly, and that's the problem. We have an ageing population and so the pressures are greater. So, it is important that we do that strategic planning for the future workforce.
