Also its one thing "looking after your own shit" ie taking your own and your immediate neighbours rubbish to the tip on your own initiative - while i think that does undermine some of the potential bargaining power of the strikers by making the clean-up less of a ever-growing problem for the council which motivates them to negotiate an end to the strike, I don't think its scabbing per se, and can understand that people don't want to live in shit. Actually if lots of people turn up to the refuse sites in cars and jam up that system, it puts pressure on the council in another way - although it might give ideas to the austerity mongers (eg why have refuse collections at all if people are willing to deliver their own rubbish to the tip!).
Its totally another thing getting together a big group of volunteers, getting donations from local businesses for gloves, hi vis, refreshments, petrol, etc and use of several commercial vehicles, arranging access to the tips with the council (because I don't think there's many councils that would usually let you turn up in a commercial vehicle multiple times without paying commercial rates) - which may well mean working alongside blacklegs and (with the way councils are nowadays) people that work for privatised contractors that certainly diminish the power of the strike even if they are not being used as scabs (and it may be that they are), and then putting out a press release and doing tv interviews, all without mentioning support for the strike.
