Once upon a time there was a middle class who believed that they were part of the ruling system. Mergers, take-overs, computerisation, the growth of huge industrial combines - all these things have pushed the middle class further away from their traditional positions of power. Now they are all workers and they need the things all workers need - organisation and power in their place of work. So says trade union leader Clive Jenkins: the middle class have turned to the trade union movement and have come in from the cold.
