Craft unions are labor organizations that represent workers in specific trades or crafts, such as carpentry, plumbing, or electrical work. These unions focus on the unique skills and training required for their members' professions, advocating for better wages, working conditions, and job security. Members of craft unions often undergo apprenticeships to gain expertise in their fields. By organizing collectively, they can negotiate with employers more effectively than individual workers could. Craft unions are a vital part of the broader labor movement, which includes various types of unions, such as industrial unions and general unions.
