(NEXSTAR) – Starbucks workers at over 110 locations across the U.S. are planning strikes or walkouts on Thursday to protest working conditions, pay, and the company’s alleged actions to discourage unionization efforts, according to a labor group representing thousands of Starbucks employees.

The walkouts are said to be the “biggest coordinated national action taken by union Starbucks stores in the campaign’s history,” with dozens of unionized locations among those where employees will be picketing, per a press release from Starbucks Workers United. 

The walkouts also coincide with Red Cup Day, a holiday-based promotion during which Starbucks provides red reusable cups to customers who make qualifying purchases.

In protest, workers at stores with strikes or planned walkouts will be hosting their own “Red Cup Rebellion,” as they’re calling it, to send a message to the company concerning its stance on benefits and unionization.

“You cannot be pro-LGTBQ, pro-BLM, pro-sustainability, and anti-union. This Red Cup Day, we’re organizing for a voice on the job and a true seat at the table,” said Michelle Eisen, a Starbucks employee from Buffalo, New York, in the press release.

More than 110 stores are said to be participating in the walkouts, Starbucks Workers United said, including coffee shops across at least 25 states, including:

  • Arizona
  • California
  • Colorado
  • Florida
  • Illinois
  • Kansas
  • Kentucky
  • Maine
  • Massachusetts
  • Maryland
  • Michigan
  • Minnesota
  • Missouri
  • New Jersey
  • New York
  • Ohio
  • Oregon
  • Pennsylvania
  • South Carolina
  • Tennessee
  • Texas
  • Utah
  • Virginia
  • Washington
  • Wisconsin

Workers at some of the Starbucks locations in those states are planning walkouts only during select or peak hours, while others appear to be planning pickets all day, materials from Starbucks Workers United suggest.

Striking workers picketing outside the locations were also planning to hand out their own branded cups in support of the labor union’s efforts.

A representative for Starbucks did not return Nexstar’s request for comment on Thursday’s strikes.

Starbucks, however, had previously said it opposes unionization efforts, claiming the company functions best when it works directly with employees, the Associated Press reported. Starbucks has denied using union-busting tactics, despite accusations of firing pro-union employees or closing shops that had voted in favor of unionizing.

At least 257 Starbucks stores have voted to unionize since late last year, according to the National Labor Relations Board. Starbucks and Workers United have engaged in contract talks at 53 stores, with 13 additional sessions scheduled, Starbucks Workers United confirmed with AP. No agreements have been reached so far.
