Starbucks Is Adopting a Surprisingly Aggressive Strategy to Discourage UnionizationThe Starbucks Union, Starbucks Workers United, has filed a complaint with the National Labor Relations Board.

InterimStarbucks CEO Howard Schultzhas resumed his post at a rocky point in the company's history, with ongoing Covid-19 concerns,supply-chain disruptions, mounting sociopolitical unrest and an increased push forunionization across its stores— which the coffee chain is continuing to fight. On May 3, Schultzannouncedthat Starbucks will invest nearly $1 billion this fiscal year alone to support increased pay, modernized training, store innovation and more — but not for unionized employees.

The investment, which follows Schultz'ssuspension of the company's buyback program, will ensure all U.S. employees earn at least $15 an hour, effective August 1, and that all employees hired on or before May 2 will receive either a $3 raise or $15 an hour, whichever is higher. Additionally, employees with two to five years of experience will receive at least a 5% increase or 5% bump above the market rate, whichever is higher, and those with more than five years of experience will receive at a 7% increase or 10% bump above the market rate.

Only employees, whomStarbucksrefers to as "partners," at the company's non-unionized stores will be eligible for the new perks. "So, partners will receive these pay, benefits and store-improvement investments at all U.S. company-operated stores where Starbucks has the right to unilaterally make these changes," the company said in a statement, perCNBC. "However, at stores where workers have union representation, federal law requires good faith bargaining over wages, benefits and working conditions which prohibits Starbucks from making or announcing unilateral changes."

The Starbucks Union, Starbucks Workers United, hasfiled a complaintwith the National Labor Relations Board over Schultz's comments. CNBC viewed a letter from Starbucks Workers United's counsel to the NLRB, which alleges that Schultz's comments "threatening to withhold" the benefits resulted in an "immediate and profound chilling effect on organizing campaigns nationwide," including a "last minute" pull of support that cost a union win at a Virginia store.

"This is not a matter of Howard's choice or opinion; this is the law," Starbucks spokesman Reggie Borges said in a statement to CNBC. "Any new benefit cannot be unilaterally given to stores that voted to unionize during collective bargaining. Howard remains focused on moving quickly to build the future of Starbucks with partners together, side-by-side."
