The historic strike of miners in the UK began following the privatisation of the sector by Margaret Tatcher, the worsening conditions and the challenge of the mining union. Most mines had a plan to close and eliminate 20,000 jobs. The strike that lasted almost a year was the longest in the UK and ended the workers’ failure. Almost every day there were incidents and the government used a dirty war against the workers. Poland sold coal to the United Kingdom to supply the lack of coal on strike.
