Birmingham bin workers have voted to continue a months-long strike, meaning industrial action could continue until December.

The dispute over pay and jobs between staff and the local Labour-run council left rubbish filling the streets of the Second City earlier this year.

The Unite union said the council told the bin workers they would face pay cuts of up to £8,000, which amounted to as much as a quarter of some staff's wages.

But a ballot on Thursday saw 97 per cent of workers voting in favour of more strike action on a 75 per cent turnout, Unite said.

A statement from the union's general secretary Sharon Graham reads: "After smearing these workers in public since January and telling them to accept a fair and reasonable offer that never existed, the council finally put a proposal in writing last week.

"True to form, the proposal came weeks late and was not in line with the ballpark offer discussed during Acas [Advisory, Conciliation and Arbitration Service] talks in May.

"It had been watered down by the Government commissioners and the leader of the council despite them never having been in the negotiations.

"It beggars belief that a Labour Government and Labour council is treating these workers so disgracefully. It is hardly surprising that so many working people are asking whose side Labour is on.

"The decision-makers at Birmingham council need to get in the room and put forward an acceptable offer.

"Unite will not allow these workers to be financially ruined - the strikes will continue for as long as it takes. Unite calls on the decision-makers to let common sense prevail in upcoming negotiations."
