Regional health managers have received details of cutbacks planned to tackle Lincolnshire's spiralling NHS debt.
Health bosses have received the turnaround plan, which gives details of redundancies and changes proposed for the Lincolnshire Hospitals NHS Trust.
The document will now be reviewed by the Trent Strategic Health Authority and the Department of Health.
A spokesperson from the trust said the plans are expected to be made public after the Spring Bank Holiday.
A memo leaked to BBC News has suggested night-time emergency services could be reduced at Boston and Grantham.
The union Unison has warned there could be as many as 1,000 health jobs lost in Lincolnshire.
Union officials have urged the trust to make the details public immediately rather than leave staff in the dark for several weeks.
NHS managers are also considering the suspension of fluoridation in the north and west of the county for a year to help reduce deficits.
They need to reduce debts of £17.5m and stem the current overspend of almost £2.5m a month.
