The strike aims to disrupt all of Glasgow City Council's services

The three-day action, set for the week after next, would hit all of Glasgow City Council's services including daycare, nurseries and social work.

Public sector union Unison has been angered by changes to the council's pay structure which they said could cost some of the members up to �9,000.

The council said they would take action to minimise disruption.

Mike Kirby, Unison's branch chairman, said the council's workforce pay and benefits review had angered members.

Next week, we will formally inform the council of our intention to strike, with a view to taking the three-day action the following week Mike Kirby Unison

He added: "There was a 2-to-1 vote in favour of industrial action in a ballot where around half of our members voted.

"Next week, we will formally inform the council of our intention to strike, with a view to taking the three-day action the following week."

About 10,000 ballots were sent out with 4,969 returned. There were 3,286 yes votes, while 1,678 people voted no.

Councillor George Ryan, the council's executive member for personnel and administration, said: "We're disappointed and surprised by Unison's recommendation, especially in light of constructive dialogue we've had in recent weeks.

"There is absolutely no need for staff to take industrial action on this issue, with the potential for loss of earnings.

"We know from working with other unions that we can quickly find solutions for any member of staff who may be worried about their take home pay.
