The Trust says its focus is now solely on improving the service to patients and better support our staff.
Vice-chair Paul Remington said: "We are developing a transformational plan, details of which will be published next week. This will involve recruiting many more front line staff, better managing sickness absence, clearer career pathways and a renewed focus on patient handover delays."
