The first overt manifestation of workers' discontent appeared in August 1979 with demonstrations by 200 women employees of the Y.H. Industrial Company, which had just gone bankrupt. Women workers occupied the headquarters of the opposition New Democratic Party and demanded the right to manage the company themselves. When the workers refused to obey the government's order to disperse, some 1,000 riot policemen raided the building. Pandemonium occurred, and one of the workers died--it was unknown whether she had jumped, was pushed, or was jostled to her death. Despite the government's efforts, the "Y.H. Incident" became a rallying cry of the opposition.
