Amazon.com Inc (NASDAQ:AMZN) shares are trading higher Thursday despite thousands of workers walking off job sites in an effort to push the company to engage in contract negotiations. Amazon reportedly said it doesn't expect operations to be impacted.

What To Know: Amazon workers at seven U.S. warehouses went on strike Thursday morning in the heart of the holiday shopping rush, per Reuters.

The International Brotherhood of Teamsters, which represents about 10,000 Amazon workers, said it was organizing the "largest" strike ever against Amazon.

"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 O'Brien.

Amazon shares were actually higher by about 1.8% at the last check. Reuters reported that Amazon said it doesn't expect the strikes to impact operations. The report indicates that unions only represent about 1% of Amazon's employee base.

The Teamsters have "intentionally misled the public" and "threatened, intimidated and attempted to coerce" employees and third-party drivers to join them, an Amazon spokesperson reportedly told Reuters on Thursday.

Amazon employs more than 1.5 million across the world and has said it prefers to maintain direct relationships with employees. The report suggests that Amazon is not likely to bargain with the union as such could make room for further union action.

Amazon announced in September that it would invest $2.1 billion to raise pay for its delivery service partner program workers in the U.S., upping base wages by approximately 7% to around $22 per hour.

AMZN Price Action: Amazon shares were up 1.83% at $224.49 at the time of publication, according to Benzinga Pro.
