Fed-up residents have told of overflowing rubbish piled high attracting 'rats as big as cats' on the streets of Birmingham - on the eve binmen stage an all-out strike. Members of trade union Unite have staged a series of one-day walkouts since January with all-out strike action due to start tomorrow, Tuesday, March 11. Workers are furious over proposals to scrap a job role affecting 170 binmen, which amounts to a pay cut of around £8,000.

Around 350 binmen will begin an indefinite all-out strike with plans to continue industrial action into the summer. More than 4,000 desperate residents have signed an online petition calling the Labour-run city council to resolve the dispute. Locals say swathes of Sparkhill, Aston, Balsall Heath and Selly Park, are already being overrun by rats feasting off rubbish and rotting food. One Tariq Mohammed, 70, who lives in Sparkhill, said: “Rubbish is always here. I have not seen any rubbish being collected for months and people just come and throw their rubbish on the street. “The smell is so bad and the rats – as big as cats - are everywhere but what can we do. “No one is listening to us, the councillors are just sitting in their office doing nothing. “No one is doing a proper job and it is the people like us who live here who are suffering.” Resident Hawida Osman, 51, said: “It’s terrible. I have seen rats coming in my house from here. “The area is already dirty and the piles of uncollected rubbish is just making the situation worse. “There are already piles of rubbish everywhere but soon it will be like a mountain unless the council do something.” Unite regional officer Zoe Mayou said: “This dispute will not end until our members are given cast iron guarantees about where the service is headed and how they will be treated within it.” The city council said it was proposing changes which would only affect 17 people and they face a pay cut of £6,000. It also said it had offered those workers promotions and training to help them improve their pay, plus "attractive" voluntary redundancy packages.
