sentences:  The strike—probably the first workers' protest since 1958, with the exception of a September 1972 strike in the Jiu Valley—began not as an anti-Communist or even an anti-Ceaușescu movement but rather a socio-economic one in spontaneous reaction to the new pensions law, as confirmed by the miners' inexperience, which led them to improvisation and hasty decision-making.However, once the Communist leaders were sequestered, it moved in a political direction and, given the repression that followed, was interpreted as such by the authorities.At the same time, the strike did have an intrinsically political character in the sense that the miners—thought of as essential components of the Communist working class—revolted against their ideological bosses and conditions created by the very political system that used them as part of its labour force.
