Amazon.com workers are organizing to join Teamsters' strikes in several U.S. states over unfair labor practices, the labor union said Thursday.

This comes after 100 Amazon drivers started a strike at the e-commerce giant's facility in Skokie, Illinois, in June.

The strikes extended to the states of Georgia, California, Kentucky and New York, the union said.

Amazon.com did not immediately respond to a Reuters request for comment.
