As a supporter of the IWCA - both as an organisation and a strategy - this is my take on the above. I'm sure others are quite capable of providing their own account.
With the collapse of the post-war social democratic consensus, and the emergence of New Labour committed to neo-liberalism, the Labour Party was (and still is) dead as a vehicle for working class political representation (let alone anything more radical); therefore something different - a new organisation - was and still is needed.
With the defeat of the miners and the NUM, the body of anti-working class industrial relations legislation and the widespread reorganisation of work itself, the workplace as a site for effecting political change no longer exists; that is why the miners and the NUM had to be defeated. But the need for collective protection, representation and advocacy at work still does; therefore unions continue to be needed.
In these circumstances, a small organisation such as the IWCA, would seem to have made the right call, i.e. organise where people live in their communities - the place where they have little or no collective voice across the whole of their lives - rather than the workplace -somewhere which by turns may not actually exist, be temporary, be precarious or even already organised.
This is not the same as saying that IWCA activists did not involve themselves in trade union activity (and taking the IWCA's politics into that activity); they did...just not as IWCA activists and not as an organisation.
So as a small exemplary organisation - that is an organisation whose purpose was to provide an experimental example of how and what to do - the IWCA targeted the identification, the promotion and the realisation of working class interests at a community level, alongside a direct attack on the Labour Party who laid claim to/relied on the lie that they were pro-working class...only they use the language of 'ordinary people' or 'hard working families'.
Given the resources at the IWCA's disposal and the small c political conservatism of virtually all those on the left who could have developed the experiment, I think the IWCA did alright. In Oxford it helped a community change some things for the better. Wherever it was active it gave Labour a fright. And it did both of these things in a consistently progressive manner. Indeed it strikes me that something similar will need to be tried again, if reactionary alternatives to the exclusion of the working class, are to be resisted.
