The trust said its Mutually Agreed Resignation Scheme has already identified approximately 100 posts, and it will do everything it can to avoid compulsory redundancies, by not replacing staff as they retire or leave. In addition, the trust said it will try to protect clinical roles.

The move is included in a new plan that will also transform the trust's services and improve patient care, which will be presented to its board tomorrow (12 June).

The trust's proposal, which is expected to detail reductions in support and corporate services, also includes:

· reducing the pay bill to minimise the use of temporary staffing, saving £24m by limiting the use of bank and agency staff, reducing overtime and not replacing leavers where possible

· an additional 5,000 operations carried out as a day case and getting people home sooner

· improved access to diagnostics through the new Community Diagnostics Centre

· Expanding theatres and improving their use with three new theatres and 18 day-case PODS to be opened in 2026

· improved environment and efficient use of buildings, including moving out of buildings that are no longer needed, investing in better buildings and progressing towards net zero carbon.

Anthony May, chief executive at Nottingham University Hospitals NHS Trust, said: ‘While we have already made significant savings of around £91m, we know there is more to do in the next three years to meet our financial targets and to help us to meet the needs of our patients and staff.

‘This will result in us having to make some difficult decisions in the coming years, in particular reducing our staff numbers by at least 430 this financial year, the majority of which will be from corporate and support services.'

In response, Unison East Midlands regional organiser Scott Weightman, said: 'Cutting jobs won't improve services for patients and will damage staff morale.

'At a time when the trust is under ever-increasing pressure, losing dedicated and experienced staff is totally counterproductive.'
