Organization of Workers

A labor or trade union is a combination of workmen organized for the ultimate purpose of securing through united action the most favourable conditions as regards wages, hours of labor, conditions of employment, etc., for its members.
In the popular sense a labor union is understood to be a completely organized body of dues-paying members, operating through elected officers and constituting a militant, vital and functioning organ. It may be said that while every labor union is a labor organization, not every labor organization is a labor union. The difference is one of organization, composition and operation.
