Amazon is facing a strike of 10,000 workers, the largest in its history, as the company is dealing with the holiday crunch.

According to the Teamsters, the strike began after Amazon executives failed to meet a deadline to negotiate with employees wages and working conditions.

“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,” said Teamsters General President Sean M. O’Brien. “These greedy executives had every chance to show decency and respect for the people who make their obscene profits possible. Instead, they’ve pushed workers to the limit and now they’re paying the price. This strike is on them.”

Employees say Amazon doesn’t care for them, despite claiming it does.

“Amazon is one of the biggest, richest corporations in the world,” said Gabriel Irizarry, a driver at DIL7 in Skokie, Ill. “They talk a big game about taking care of their workers, but when it comes down to it, Amazon does not respect us and our right to negotiate for better working conditions and wages. We can’t even afford to pay our bills.”

Amazon is notoriously anti-union, going to great lengths to undermine organizing efforts, including hiring Pinkertons to monitor such employees. The company has faced repeated criticism for its stance, with its own investors advising the company to tone down its efforts, and a US judge ordering the company to cease its anti-union retaliation.

Despite Amazon’s well-known stance, employees are counting on the equally well-known reputation of the Teamsters union to help them.

“I’ve seen the Teamsters win big battles,” said Dia Ortiz, a worker at DBK4 in New York. “We’re ready to do what it takes to win this one.”

Only time will tell if the strike has any effect.
