As anyone who worked during the 1970s will remember hardly a day went by without news of another industrial dispute.

And in the 60s, we had 20 years of successive governments both Labour and Tory struggling to deal with the unions culminating with the 'Winter of discontent', not helped of course by inflation.

I remember working with the factory windows being covered in black polythene in order that the surrounding neighbourhood would not know that unlike them, we had power.
