Major cuts to health services in Lincolnshire will put a massive strain on the county's carers, it is claimed.
To recover £8m of debt, the United Lincolnshire Hospitals NHS Trust wants fewer people to be admitted to hospital and earlier discharges.
The financial plan also involves the closure of five hospital wards and the loss of 300 jobs.
But some carers are worried the burden will shift on to unpaid carers and social services.
But Tim Barjitsky, from Share the Care, said: "If (the carers) have other commitments or jobs during the day, what are they going to do?
"With people spending less time being looked after in hospital, where else is the job of looking after people going to go?"
Jenny Green, chairman of the United Lincolnshire NHS Trust, insisted there should not be compulsory redundancies among font line staff.
She said: "We are still developing services, we are not cutting back services.
"But where people can be treated more appropriately and - dare I say it - more cost effectively - nearer to their homes that is surely something everyone can welcome."
Richard Parker, from the trade union Unison, said: "We need every single nurse, every single ancillary worker, we need every single admin and clerical worker because they provide the quality services that support patients in the hospital and in the community."
