Trillium Asset Management, which holds $48 million of Starbucks stock, is leading the charge on behalf of a billion-dollar-plus group of investors to push the coffee retailer to adopt a "union neutral" stance.
To date, more than 130 Starbucks stores in 26 states have petitioned the NLRB to unionize. Of the seven stores that have held elections so far, six have voted to unionize.
According to the letter sent to both Mellody Hobson, Independent Chair of the Starbucks Board of Directors, and Kevin Johnson, its CEO (and obtained by CNBC), there exists grave investor concern that reports of Starbucks' "aggressive union-busting tactics" will harm the brand and its reputation (and, by extension, sales, profits, and, ultimately, share value).
