CHESHIRE West and Chester Council could be hit by industrial action including a possible strike.
No less than 76.45% of council staff who are Unison members voted in favour of industrial action short of a strike over the authority's imposition of new terms and conditions.
While 65.29% of the 896 members who voted are prepared to go on all out strike.
The council says the changes are necessary to equalise terms and conditions between employees of the four legacy authorities which were replaced by CWaC in 2009.
Unison has talked about the possibility of staff withdrawing the use of their personal cars because of a cut in car allowances.
Another option is a ban on overnight 'sleep overs' for certain care workers. Library staff may strike on Saturday mornings because of the loss of enhanced payments for weekend working.
Ray McHale, assistant branch secretary of West Cheshire Unison, said: "We worked with the council on their original proposals and were prepared to harmonise all terms and conditions. Our members are aware the council decided to throw all that out and force changes on to staff which are worse than those originally proposed.
“The economic climate is being used as an excuse to worsen staff terms and conditions yet the council can find money for headline grabbing projects. That cannot be right and yet it is the choice this council has made.”
The authority claims 96% of the workforce has signed up to the new contracts which will save £3.9m a year for reinvestment into front-line services. Those who do not accept the changes will be dismissed and rehired under the new terms.
