About 560 Starbucks locations have voted for union representation since the first vote to unionize four years ago, according to the union Starbucks Workers United.
The Teamsters won a ban on any further outsourcing, wrested back some previously outsourced jobs, and for the first time won the right to honor strikes by other Kroger Teamsters.
The milestone comes some six months after a failed high-profile union bid by Amazon workers in Bessemer, Alabama, who sought to be represented by the Retail, Wholesale and Department Store Union.

The investors calling for Amazon to cease pushing back on the unionization efforts collectively hold more than $20 billion worth of the company's shares.
