A Union can represent workers in just about every industry. There are two major types of unions: Industry (Teachers, Autoworkers, Police, etc) and Craft/Skilled Trades (Electricians, Ironworkers, Boilermakers, etc). These types have some VERY essential differences. Most, if not all, Industry Unions represent workers after they have been hired by the Employer -- they don't actually get you a job. Many of the Craft Unions are Full Referral, which means the Hall dispatches members to work for signatory companies (ones who have a CBA with the Union) when they need workers.
