miners strike under Joe wat his name to bring down an elected government
I think you may be thinking about Joe Gormley who was Arthur Scargill's predecessor. TBH in the 60s and 70s mining was a very dirty, dangerous job which wasn't that well paid, relative to the risks - Gormley tried to correct this by balloted strike action in 1972, the first time the miners had been out officially since the General Strike of 1926. It should be remembered that at the time of this 7 week strike the miners had massive support from other union members in the UK. The Wilberforce Inquiry, which was set-up by the government at the time reported that they knew of
"...no other job in which there is such a combination of danger, health hazard, discomfort in working conditions, social inconvenience and community isolation."
The government which was brought down was in fact Ted Heath's administration of 1970 to 1974 and it wasn't just the miners who were his undoing - it was also his attempt to bring in The Industrial Relations Act, widely detested by the trades unions, coupled with the 3 day week (the result of the 1974 miners strike) and his attempts at doing a deal with the IRA (which cost him the votes of the Ulster Unionists).
You've got to remember that inflation in the early 1970s was truly horrendous (double digit) and as it increased, miners' wages fell in real terms, so by late 1973 average miner's wages were 2.3% lower than recommended by the
Wilberforce Inquiry (see above) and falling steadily. The union didn't however strike immediately (the members balloted almost 2:1 against striking in October 1973) but in early 1974 they implimented an overtime ban which more or less halved production, and that underlined the lack of manpower in the industry - or put simply, many who could do another job never wanted to go down the pit, regardless of money.
In February 1974, with the NCB (and government) refusing to budge, the miners went on strike, and the 3 Day Week happened. Heath called an election using the slogan,
"Who governs Britain?". But he couldn't form a majority government, so that snake Harold Wilson formed the next (Labour) government
So you see, Joe Gormley and the NUM didn't bring down the Heath administration alone - that is a lie which has been told and retold by the ignorant (of the facts) right wing press and the Tory Party. The pity was that we really needed to have stronger workers' rights (which Labour did partially address in the 1975 Employment Act) coupled with stronger
and compulsory (on both sides) industrial arbitritation (which they didn't)
This is a complex and oft misunderstood period of British politics. I lived through it, I was an active union member, and it still confuses the hell out of me at times!
