Unions are workers who stand together to bargain with their bosses for better pay, safer working conditions and decent benefits.
Historically, unions have accomplished many things for all working people that we now take for granted. Things like the eight-hour work day, minimum wage, child labor laws, unemployment insurance, Social Security and worker health and safety laws all were the direct result of union advocacy. Even Labor Day was created by unions.
