Some 7,000 council workers in Kirklees Unison union, West Yorkshire, were set to start balloting for strikes against compulsory redundancies from Thursday of this week.
Council bosses there talk about a fiscal cliff—£24 million cuts next year and mass sackings.
Kirklees Unison has every year reaffirmed its policy to strike if bosses impose compulsory redundancy on anyone.
This has meant that the council has avoided compulsory redundancies while pushing people out through voluntary redundancy and early retirement.
The council gave a commitment that there would be no compulsory redundancies, but would not extend the agreement to Unison members employed in schools.
The Kirklees branch could not sign up to such an agreement.
The council went ahead and sacked two members at Ashbrow school in Huddersfield in January.
We immediately called for a strike ballot.
The ballot was delayed as the council promised talks. After four months a ballot has now been agreed.
Action is due to start the week commencing 23 July.
