Trucker in a Union is a job title that refers to a truck driver who is a member of a labor union. The term is often used interchangeably with TEAMSTER, which is an 8-letter word that is used to describe a trucker in a union. Teamsters are members of the International Brotherhood of Teamsters, a labor union that represents workers in many industries, including trucking. Teamsters are protected by collective bargaining agreements and have access to benefits such as health insurance and retirement plans.
