The National War Labor Board (NWLB) was an agency of the United States government established during both World War I and World War II. Its primary function was to mediate labor disputes that could potentially disrupt war production. By providing a forum for negotiation and arbitration, the board aimed to prevent strikes and lockouts, ensuring a steady supply of war materials. For instance, if a union and a factory owner disagreed over wages or working conditions, the NWLB would intervene to reach a compromise acceptable to both parties.
The existence and actions of this entity significantly impacted the American labor movement. It provided unions with a degree of recognition and influence they had not previously possessed on a national scale. In exchange for labor’s commitment to avoiding strikes, the board often pressured employers to improve wages, working conditions, and recognize the right to collective bargaining. This, in turn, strengthened unions and expanded their membership. Its activities demonstrated the government’s willingness to intervene in the economy to support the war effort and maintain social stability.
