Many blacks moved from the south to northern cities during world war ii looking for employment. after the war, a number of them lost their jobs. why did this happen?

They got the jobs because their was a shortage to the amount of workers there were, and so the companies couldn't be discriminate, because they got merchandise to make. However, after the war, many of the Americans returned, and the businesses wanted to give the jobs back to the White Americans, so they fired many of the African Americans that were previously holding the jobs during the war

hope this helps
