The Great Migration was the relocation of more than 6 million African Americans from the rural South to the cities of the North, Midwest and West from about 1916 to 1970.
Part A: Working hours changed from around 14 hours a day before the 1880's to being reduced slowly down to 12, then 10, eventually moving to an 8 hour day. This change allowed for workers to to have more time to sleep and for leisure. Another change was the end of child labor. Similar to the decrease in hours, the minimum age increased over time as well moving from 10 to 16.
Part B: One strategy used by unions to achieve these goals were strikes. Workers would leave the job and picket outside of a job which shut down operations. This tactic did not work at first because there were plenty of workers to fill the jobs. However, when immigration slowed the tactic had more impact with no people to fill the jobs. Some strikes were so large they brought the attention of police forces and the government.
