"In the spring of 1943, what did employers started doing?"

Following the stock market crash of 1929, the Hoover Administration urged and many industries and unions adopted work-sharing. For example, the United States Steel Corporation in 1929 had 224,980 full-time employees. The number shrank to 211,055 in 1930, to 53,619 in 1931, to 18,938 in 1932, and to zero on April 1, 1933. All who remained on the payroll on this last date were part time, and they were only half as numerous as those on full time in 1929.

Explanation:

The Hoover government desperately encouraged and many companies and labor unions embraced a shared job during the stock market collapse of 1929. For eg, in 1929 there were 224,980 full-time workers in the United States Steel Company. In 1930, the number declined to 211,055; in 1931, 53,619; in 1932, 18,938; in April 1933, to 09. The last day was a part-time payroll and about about as many as the full-time payrolls of 1928 were still in use.

i believe it may be the hope this sorry if i'm wrong.

the writer needs to avoid using abbreviations and check spelling before sharing.
