Boston Borough Council is to make savings of about £10,000 a month following the departure of its chief executive Richard Harbord in November.
Surrey-based Mr Harbord was on a £121,500-a-year contract, working 15 days a month.
He resigned in September due to family commitments.
The council’s deputy chief executive Phil Drury has been appointed acting chief executive until a permenant replacement for Mr Harbord can be found.
As a result, from this December, the council will save about £10,000 a month. Mr Drury is being paid an extra £500 a month for taking on the extra responsibility.
At last Monday’s meeting of full council, members were told Mr Drury could stay in the role for up to a year – or until somebody else is appointed.
The chief executive post is a statutory role at the council under the Local Government and Housing Act.
