A group of Apple employees is circulating a written petition demanding an investigation into the hiring of Antonio Garcia Martinez, who was brought on to join the company’s product-engineering team for ad platforms, over views deemed “misogynistic” and “overtly racist.”

In the petition, the employees said Garcia Martinez’s hiring called into question Apple’s “hiring panels, background checks, and our process to ensure our existing culture of inclusion is strong enough to withstand individuals who don’t share our inclusive values.”
