8. Although we tend to think of labor unions as representing manufacturing employees, many office and service industry employees, teachers, and professionals belong to unions. Visit the Web sites of two of the following nonmanufacturing unions and discuss how they help their members: the Office and Professional Employees International Union (http://www.opeiu.org), the American Federation of State, County and Municipal Employees (http://www.afscme.

org), the National Education Association (http://www.nea.org), the Actor’s Equity Association

(http://www.actorsequity.org), and the American Federation of Musicians (http://www.

afm.org). What are the differences, if any, between these unions and those in other industries?
