The union warned that Rotherham will not be the last hospital to announce cuts as many are struggling to cope with the impact of funding cuts, rising patient numbers and the legacy of Private Finance Initiative debt.
"This is terrible news for patients and for the local community who will lose vital health services. Cutting nursing staff at a time when we have an ageing population and have already lost nearly 6,000 nurses since the ConDems came to power should worry everyone who relies on the NHS in Rotherham.
