What are some early labor unions?
National Labor Union and Knights of Labor.
The first labor union was the National Labor Union. It was organized in 1866. Another early labor union was the Knights of Labor. This union was secret society when it first began in 1869. The American Federation of Labor was an early labor union that was led by Samuel Gompers and was established in 1886.
The general attitude toward labor unions will vary from class to class. Some will be very supportive of labor unions, some won't, and some will be split. Attitudes will probably largely be based on whether or not labor unions have a positive effect on the person and/or members of their families, or whether or not a person believes the unions have a positive effect on society as a whole.
