In the 1980s the British government passed several laws to restrict the power of the unions. One of these abolished the 'closed shop' (arrangement which employers made with unions to hire only people who belonged to a union). Another made strikes illegal unless a postal vote of all union members had been conducted. In 1984 there was a long miners' strike. The National Union of Miners refused to follow the new regulations. Its leader, Arthur Scargill, became a symbol (depending on your point of view) of either all the worst lunacies of unionism or the brave fight of the working classes against the rise of Thatcherism. Previous miners' strikes in the twentieth century had been mostly successful. But this one was not (the miners dad not achieve their aims); a sign of the decline in union power.
