A documentary made at a time when feminist theory on unequal pay was in its infancy, this gets at the heart of the problem with considerable precision. For instance: why are women workers often employed in declining industrial sectors? Answer: cheap labour and minimal plant investment go together. 'It's more profitable to employ women than to automate a plant. It's cheaper to sack a woman than to keep a machine idle'. With Britain in the throes of 'de-industrialisation', there are lessons here for more than just women.
