LittleSarah is right that it's one sided. I am in general on the side of kids who get burned as against rich thugs. Fact that I was a burned kid, is extra.
What do you think happens when you turn off the power to poor people's homes ?
Sit around the camp fire singing jolly folk songs ?
Why do you think Thatcher was elected ? She was personally very unpopular even before she was PM. Ordinary people were sick of being kicked around, and I mean that quite literally. There was open talk of serious violence, way beyond the standard union actios of tossing lumps of concrete onto motorways to "show support".
In any case, LittleSarah, I was very careful to give dates. Thatcher was not in power in the 1970s, indeed half the miners strikes were against the fact that even the Labour government they hired thought their demands were excessive.
In effect the final Labour government was sacked for not doing what it's employers told it to do.
Recall that even now many Labour MPs are in effect employees of unions. In the 1970s the party was a creature of the unions, and they even squatted in the offices of one of the bigger unions.
The strikes for really quite amazing levels of pay were in the 1970s when Thatcher was variously minister of education or an opposition MP. Doubt if most miners knew she existed then.
Thatcher's actions were quite probably motivated by revenge since the miners had brought down at least one tory government as well.
But it needed to happen. If you allow gangs of armed thugs to declare areas of country no go areas, and cut off it's electricity supply at a whim, it is going to end badly.
As for the "closed shop". This was where you had to belong to a union else you were sacked, or not hired. That meant up until the 1990s that women and "coloureds" were shut out of several employers, or else not allowed to take jobs that belonged to white men like (err umm) me.
If you fell out with your shop steward, he could have you sacked, and no there was no unfair dismissal, race or sex discrimination act to protect you. Note that unions have all sorts of legal immunities, wonder how they got there ?
If, as we saw at Grunwick you were unwise enough to be an asian woman, it was stupid of you to expect that you could take a white union man's job. If necessary they would use violence to stop you.
