The primary functions of a trade union are to protect, defend and support the common interests of members by acting as a mediator between workers and the organizations for whom they work. The first trade union in the United States was organized in 1794 in Philadelphia by a group of shoemakers. The purpose was to establish a common wage system in order to prevent employers and unskilled workers from undercutting members.
