1. Major League Baseball Players Association (MLBPA). This union represents professional major-league baseball players. The MLBPA was not the first attempt to unionize baseball players; there were 4 other attempts before the MLBPA was created in 1953. In 1968 Marvin Miller headed the organization and negotiated the first collective bargaining agreement, raising the minimum salary from $6,000.00 to $10,000.00 per year (Wikipedia, par. 1). The professional players may be unionized to ensure that they are guaranteed their pay if they get hurt and can no longer finish the season, or they may want a no trade agreement so the owners would not be allowed to trade them to another team at any time during the contract.
2. American Federation of Teachers (AFT). This union represents teachers, paraprofessionals, and school related personnel; local, state and federal employees; higher education faculty and staff; and nurses and other health care professionals. The AFT members consist of members who teach or work in school related occupations (i.e.: teachers, school librarians, etc.), as well as nurses, dentists, and doctors. The AFT was founded in 1916, and is now the second largest education labor union in the United States, representing about 1.5 million members as of 2010.(United States History,
