Starbucks is planning to follow up on its CEO’s promise to implement “unconscious bias” training by closing more than 8,000 company-owned stores across the U.S. on May 29 to conduct “racial bias training,” per a Starbucks news release.

“I’ve spent the last few days in Philadelphia with my leadership team listening to the community, learning what we did wrong and the steps we need to take to fix it,” Starbucks CEO Kevin Johnson said in the statement.

“While this is not limited to Starbucks, we’re committed to being a part of the solution. Closing our stores for racial-bias training is just one step in a journey that requires dedication from every level of our company and partnerships in our local communities.”

Company-owned retail stores, as well as corporate offices, will close for the afternoon of Tuesday, May 29, for employees to undergo training designed to “address implicit bias, promote conscious inclusion” and deal with discrimination issues, the news release confirms.

Moving forward, this curriculum will become part of routine training for all new Starbucks hires, the company says.

Starbucks-licensed outlets, such as those found in colleges or supermarkets, or inside other retail outlets, are not included among the 8,000-plus company-owned stores confirmed to be closing in Starbucks’ announcement, and not required to close. However, as a spokesperson for Fox News confirmed, the curriculum will be available to those outlets, and licensed stores will be encouraged to participate in the training.

“We will learn from our mistakes and reaffirm our commitment to creating a safe and welcoming environment for every customer,” added Starbucks Executive Chairman Howard Schultz in the company’s announcement.

News of Starbucks’ mass training efforts comes in response to an April 12 incident during which two African-American men were arrested while waiting for a friend inside a Philadelphia Starbucks around 4:30 p.m. Employees reportedly claimed the men were trespassing, and police later led both away in handcuffs. Johnson called the incident “reprehensible” and said the arrests never should have happened, according to the Associated Press.

While the two arrested men have yet to be identified by name, the AP confirmed Johnson met in person with the pair April 16 to apologize.
