THE Teamsters union launched the biggest strike against delivery giant Amazon in US history today.

Workers walked out at seven facilities in California, Georgia, Illinois and New York City, with the union saying members at hundreds of others are “prepared to join” the strike wave.

“If your package is delayed during the holidays, you can blame Amazon’s insatiable greed. We gave Amazon a clear deadline to come to the table and do right by our members. They ignored it,” Teamsters president Sean O’Brien said.
