In 2015, the beauty retailer Sephora made its brand tagline “Let’s Beauty Together,” switching away from a prior mantra, “The Beauty Authority.” Its senior vice president for marketing and brand, Deborah Yeh, explained the tagline several years later: “Beauty is diverse and has many voices and faces,” she said. “We believe it’s for our clients to define and for us to celebrate.”

In late April, the R&B star SZA, who is black (and has said she worked at Sephora before she made it as a musician), reported that a Sephora employee in Calabasas, Calif., had “called security to make sure I wasn’t stealing.” The news threatened to upset that carefully honed, diversity-focused image, which has resonated with the brand’s young American customers.

On Wednesday, Sephora will close all of its stores in order to host a “one-hour inclusivity workshop” for employees at retail locations, distribution centers and corporate offices in the United States. The brand announced these plans in the caption of a Facebook video several weeks ago. Separately, the brand apologized to SZA, and said it was “working with our teams to address the situation immediately.”

The training comes in tandem with the release of a Sephora “manifesto,” entitled “We Belong to Something Beautiful,” that is meant to outline the brand’s commitment to championing diversity and self-expression. “While it is true that SZA’s experience occurred prior to the launch of the ‘We Belong to Something Beautiful’ campaign, the campaign was not the result of this Tweet,” said a statement released by Sephora. “However, it does reinforce why belonging is now more important than ever.“ The company had been planning the one-hour workshop for its 16,000 employees for more than six months, the statement explained.
