The union is aiming to pressure the online retailer by threatening delays in package deliveries during the critical holiday season.

Union organizers have called an end to a five-day strike against Amazon by about 100 Atlanta drivers who joined workers at hundreds of other locations around the country.

A spokesperson for Amazon said the union claims they represent “thousands of Amazon employees and drivers” when they don’t.

The Teamsters' strike against Amazon began Thursday morning at several facilities in New York City, Atlanta, California, Illinois and elsehwere.

Amazon workers have walked off the job at seven facilities throughout the U.S., including the company's Queens location in New York City, as they push for contract talks with their union.

Amazon workers at four California facilities will join their striking colleagues on the picket line Thursday morning after reaching a stalemate during labor negotiations.

Bundled up and huddled around propane and diesel heaters, the group appeared upbeat and optimistic as strike organizers provided them with hats, jackets, hand warmers, beverages and snacks.

The International Brotherhood of Teamsters said workers at seven Amazon facilities will begin a strike on Thursday morning.

Striking Amazon and Starbucks workers are on picket lines instead of delivering last-minute presents or handing customers Christmas-themed drinks, as their unions pressure the companies during the holidays -- and before a less union-friendly president is sworn into office.

Amazon and Starbucks workers strike for union recognition and better working conditions. Labor leaders prepare for potential rollback of worker protections under Trump administration. California unions seek state-level safeguards against weakening federal labor regulations.
