bosses were aware of West's problematic behavior but turned their moral compass off
Adidas does not know if the allegations are true.
The company said in a statement that it was not clear if the accusations made in an anonymous letter were true.
We have decided to launch an independent investigation to address the allegations.
West was dropped by the company last month after he posted anti-Semitic comments online.
Rolling Stone reported allegations from anonymous staff members that he tried to intimidate them through provocative, frequently sexualized, and often directed towards women.
It was reported that he showed them explicit images of his ex- wife.
According to the letter, staff members complained to Adidas about the toxic and chaotic environment that West created and a very sick pattern of predacious behavior toward women who worked for him.
According to Rolling Stone, the letter said that he had "exploded at women in the room with offensive remarks and would use sexually disturbing references when giving design feedback." Adidas employees should not be subjected to this type of response from a brand partner.
West has yet to comment on the claims. West has been contacted by the ABC.
