Amazon has told employees to delete the popular video app TikTok from phones on which they use Amazon email, citing security risks from the China-owned app, according to reports and social-media posts by Amazon employees, and escalating the stakes for TikTok, which has been subject to national-security and geopolitical concerns. The notice said employees must delete the app by Friday to keep access to Amazon email. Amazon is the second-largest U.S. private employer after Walmart, with with more than 840,000 employees worldwide. Amazon and TikTok did not immediately reply to requests for comment.
