With respect, you were not in unison with your fellow mineworkers. You were in unison with those who agreed with you upon whether there should be a strike. You don't know if you were in unison with the majority of your fellow mineworkers, because the NUM leadership denied them the secret ballot that the unions constitution guaranteed them. They denied them a ballot because they were scared that they might not get the result that they wanted, which was a confrontation with the government.
Rather than receiving the benefit of any form of ‘unison’ your fellow mineworker’s who did not share your view upon whether there should be strike faced intimidation both at their places of work and at their homes and elsewhere. Some may feel that was justified or acceptable, whereas I don’t. The leadership of a union should act upon the wishes of the whole membership, not just those members who agree with them.
Yes, Thatcher wanted the confrontation and prepared for it. The reason for that is that the unions had acted recklessly and unreasonably throughout the 60s and 70s and had caused immeasurable damage to the UK economy and the government was determined to end that. The NUM leadership knew that very well and were also playing a political game. Mining communities paid a huge price for it.
