Some 40 traffic wardens, maintenance engineers and cash collectors will strike for seven days in Southampton.
The workers, in the Unison and Unite unions, are the next group to strike in the campaign against pay cuts in the council.
They struck from Tuesday—the day the refuse workers returned to work after a successful five-day strike.
The refuse workers will walk out again for one day on Saturday.
They are also refusing to work overtime and are working to rule.
The industrial action short of a strike continues and is being well supported.
The council has stated that it will join talks with trade unions and Acas, but no steps have been taken to organise this.
A joint rally to support the action is to be held on Thursday of this week. Speakers will include Keith Sonnet, Unison deputy general secretary, and Len McCluskey, Unite general secretary.
With the growing industrial action, financial support is crucial.
Other sections are preparing to strike when parking operations returns to work.
The unions are paying full take home pay to those on strike, plus hardship payments to members refusing to work overtime.
Everyone who supports the strike should donate to the unions’ funds and send messages of support.
Joint Unison and Unite meeting, 2 June, 12.30pm, Above Bar Church, Southampton SO14 7FE.
