(Bloomberg) –LinkedIn’s senior executive in charge of human resources has resigned after breaking “compliance” rules, according to people familiar with the matter.

Christina Hall left the Microsoft Corp.-owned company because of an internal “compliance” issue, the people said, asking not to be identified because the details aren’t public. LinkedIn Chief Executive Officer Jeff Weiner announced the move to staff on Tuesday, they said.

“Nina McQueen will lead our global talent organization on an interim basis while we conduct an internal and external search for a replacement,” said Ngaire Moyes, spokeswoman for LinkedIn, in an emailed statement on Wednesday, declining to comment further.

Hall, who had been at LinkedIn for six years, led the company’s human resources team, and oversaw hiring and benefit programs at the company. A former lawyer, she previously held roles in the compensation departments of Facebook Inc. and Intuit Inc., according to her LinkedIn profile. She’d held her current title since September 2018.

She didn’t immediately respond to a request for comment.

Microsoft acquired LinkedIn in 2016 in an all-cash purchase valued at $26.2 billion.
