automakers nearly every year, usually due to disagreements over wages, benefits, and work conditions. Auto workers often demand higher wages and better benefits. They may also demand safer working conditions or improved job security. Union leaders and automakers negotiate and bargain over the terms and conditions of the contracts, such as the length of contracts, economic issues, and other work-related issues. In some cases, if the automakers and union can’t come to an agreement, the workers may choose to go on strike. In the most extreme cases, a nationwide strike can occur, particularly when negotiations involve workers at multiple locations.
