KEY POINTS
  • Former TikTok employees say there is cause for concern when it comes to the popular social media app's Chinese parent company.
  • They say ByteDance has access to TikTok's American user data and is closely involved in the Los Angeles company's decision-making and product development. 
  • Some cybersecurity experts worry that the Chinese government could use TikTok to spread propaganda or censorship to American audience, or to exercise influence over users who may come to regret what they posted on the service.

A former TikTok recruiter remembers that her hours were supposed to be from 10 a.m. to 7 p.m., but more often than not, she found herself working double shifts. That's because the company's Beijing-based ByteDance executives were heavily involved in TikTok's decision-making, she said, and expected the company's California employees to be available at all hours of the day. TikTok employees, she said, were expected to restart their day and work during Chinese business hours to answer their ByteDance counterparts' questions.

This recruiter, along with four other former employees, told CNBC they're concerned about the popular social media app's Chinese parent company, which they say has access to American user data and is actively involved in the Los Angeles company's decision-making and product development. These people asked to remain anonymous for fear of retribution from the company.
