The First Minister knows that I've been raising concerns recently about staffing at Ysbyty Gwynedd, and rotas there clearly continue to be a problem. One recent e-mail from staff refers to the Hergest mental health unit, with staff morale at an all-time low, poor recruitment and retention, high sickness and poor working conditions. The result: more and more use of agency staff. When will the Welsh Government really get to grips with this unsustainable and expensive overreliance on agency workers and the rota difficulties that that perpetuates? This is resource that should be spent on supporting and improving working conditions for staff at Ysbyty Gwynedd and hospitals the length and breadth of Wales.
