Although the thread has moved on a bit from discussing AAVA's, I've just come across an interesting passage in Christopher Lee's history of Great Britain 'This Sceptred Isle'. Talking about the derisory pay offers being made in 1973 he states:
"In response, coal miners banned overtime working - by the end of the year there was a 40% shortfall in coal supplies to power stations - leading to an energy crisis that caused the government to declare a state of emergency".
Admittedly that overtime ban came direct from the NUM leadership, not something Prospect would ever do, but it does show how much industry relies on overtime, and the effects of refusing to work extra hours.
