The Builders Laborers Federation was a union in Australia, representing those workers without a trade who did all the hard yards on the building site.
Through their strong community links, they heard lots about the effects of inappropriate development on normal folks, and came up with the "Green Ban" as a response.
They simply refused to work on projects that were socially or environmentally damaging. The effects of the Green Bans are still around today - the historic district of the rocks in Sydney is only there due to BLF action.
The BLF was deregistered by the government of the day, and smashed.
One of the things to come out of the rubble was the Earthworker Co-operative, which is designed to transef the ownership and control of work itself into the hands of the workers.
We hope you enjoy this interview.
