When a union is composed of workers with the same skill, it is called a craft union. This means that the union represents workers who have the same type of training or expertise in a particular craft or trade. For example, a union of electricians, plumbers, or carpenters would be considered craft unions. These workers often have specific skills that are honed through years of training and experience, and the craft union helps to protect their interests, such as negotiating better wages, benefits, and working conditions. By focusing on a specific skill, craft unions can advocate for their members' unique needs and ensure that they receive fair treatment in the workplace.
