Staff earning more than £25,000 at Cambridgeshire County Council will be forced to take three days of unpaid leave at Christmas this year in order to save £900,000.
The move was revealed in a letter to party leaders by Gilliam Beasley, chief executive of Cambridgeshire County Council.
The letter, reported in the Cambridge Independent, said council staff contracts have a “provision of mandatory unpaid leave” which was negotiated with trade unions a few years ago.
She said the provision was “only to be applied if the council faced significant financial difficulties, which we are undoubtedly facing now”.
In August, Somerset County Council announced a similar move, which was opposed by unions.
