Nike’s vice president of footwear, Greg Thompson, has left the company, a Nike spokesman confirmed to Reuters.

Earlier this week, Nike confirmed reports that Vikrant Singh, Nike’s senior brand director for basketball in North America; Daniel Tawiah, Nike’s VP of global brand digital-marketing innovation and Antoine Andrews, Nike’s vice president of diversity and inclusion, had all left the company.

The exits come after allegations of inappropriate workplace behavior led to changes in March in Nike’s executive ranks. Nike declined to provide any reasons for the exits this week.

In mid-March, Nike announced that the resignation of Trevor Edwards, Nike Brand president, and the firing of Jayme Martin, VP and general manager of global categories for Nike Brand, due to workplace complaints. Nike said at the time of the dismissals that it was conducting a review of the company’s human-resources systems and practices for elevating internal complaints
