How many industrial revolutions have women experienced when they entered the workplace?

The second time. Women entered the workplace mainly in the period of the second industrial revolution, which began in the 1970s from 65438 to 2009, and brought great inventions such as electrification, internal combustion engine, chemical industry and communication means. During this period, with the expansion of production scale and the improvement of production efficiency, the demand for labor also increased. Electronization enables women to give full play to their prudent advantages, and women's rights prevail, and equality between men and women prevails. It should be noted that due to the influence of traditional ideas and social structure, women's role in the family is regarded as more important, so they rarely have the opportunity to participate in external work.
