“All the nurses want to do is what they’ve done for decades. We’ve got nurses that have been intensive care for 30 years which is to carry on providing excellent treatment to their patients.
“I think the trust is really potentially going to lose a lot of valuable expensive and skill by forcing these changes on the nurses,” Mr Rawlinson said.
The union also said the nurses fear the rotation would lead to Bassetlaw Hospital losing its ICU permanently.
Karen Jessop, Chief Nurse at DBTH, said: “Our priority is patient safety, and that means ensuring our highly skilled ICU nurses maintain the level of competency critically ill patients rightly expect.
“Bassetlaw Hospital sees fewer very sick patients, and a short-term rotation with Doncaster is the safest and most effective way to keep those specialist skills up-to-date.
“We have worked closely with colleagues and unions, and we believe our offer is practical, supportive, and focused on enabling our teams to continue delivering the safest, highest-quality care.”
