Amazon is now facing a labor threat from the Teamsters union

Amazon is facing another union battle — and this time it could go nationwide.

The Seattle-based e-tailing giant — which in April fended off a closely watched attempt to unionize a warehouse in Alabama — is now facing a threat from the powerful Teamsters union, which on Thursday will vote on a resolution to organize thousands of Amazon drivers and warehouse workers across the country. At its annual convention, leaders of the International Brotherhood of Teamsters are expected to adopt the initiative to fund and assist workers in securing a labor contract at Amazon amid global pressure on the retailer to improve wages and working conditions.
