The statement is correct because during the Gret Migration of 1916-1930 an estimated one million black people migrated from the south to the north for better livelihood.
Explanation
- People of Afro- American origin had been very instrumental in carving a niche during the Labor movement. They had played a very important role in giving new lease of life to this movement. They participated very actively in several labor-related actions and movements before the days of civil war.
- The Washington Navy Yard strike in 1835 by bulk caulkers is n example of how they were up against it. It needs to be remembered that caulking which means to cover leakage in pipes and other rubber structures was taken up as an important profession for the people during that time. Most of the caulkers belonged to Afro-American tribe and caulking was the source of living for them
- Once the civil war ended lots of amendments and reformation was brought about including new labour law and new labor system however the rel event concerning labor movement occurred from the year 1916-1930 which witnessed an extremely high percentage of people from the south migrating towards North and west. This because of the Afro- Americans wanted a better life and a better future. As per estimates, over four lakh people migrated from 1916-1918 to make the most of the labor shortage which happened s a result of world war I. Subsequently this helped in stepping up labor movement in the north and more fro Americans got better and good employment opportunities in different sectors.
