Step-by-step explanation:
The National War Labor Board adopted the practice of equal pay for equal work in November of 1942 to ensure fair treatment for women in the workplace during the war.
Due to the departure of wage-earning men for the war effort, more than one million women entered the workforce for the first time, and over eight million working women found higher paying jobs, often in industry. However, women were typically paid lower wages than male workers, even when performing the same work.
The adoption of equal pay for equal work by the National War Labor Board aimed to address this wage disparity and ensure fair treatment for women in the workplace during the war.
