Microsoft is under investigation by the U.S. Department of Labor for setting employment diversity targets.

Tech giants Facebook, Amazon, Apple and Google have all been declared monopolies in their respective areas of strength, but Microsoft has not yet escaped regulatory scrutiny entirely. The company is currently under investigation by the U.S. Department of Labor over concerns about racial diversity in its employment. But unlike the discriminatory issues that people think, the Labor Department is focused on Microsoft’s goal of increasing black representation in the company.

Microsoft is under investigation by the U.S. Department of Labor for setting employment diversity targets.

Microsoft said it had been contacted by the U.S. Department of Labor’s Office of the Federal Contract Compliance Program (OFCCP) about the company’s recent commitment to increase black representation in its workforce, including a bid to double the number of blacks it employs in leadership positions by 2025. The Labor Department’s letter suggests that this commitment could violate the Civil Rights Act.

The news, which is being investigated by the Labor Department, comes after the Trump administration tried to use the executive order to prevent government contractors from providing certain types of diversity training.

Microsoft defended its approach, saying, “We fully believe that Microsoft’s diversification efforts are fully compliant with all U.S. employment laws,” Dev Stahlkopf, Microsoft’s general counsel, said in a blog post. “We look forward to providing this information to the Department of Labor and, if necessary, defending our approach.”
