For the first time, former TikTok worker Lynda Ouazar is speaking out to expose what she says was an environment of bullying, harassment and union-busting at one of the world's biggest social media companies. "I was finding it really hard to sleep at night, having flashbacks, feeling tired, losing my motivation," she told Sky News. Along with four of her former colleagues, she is now launching legal action against TikTok. This is the second court case TikTok is facing from former UK employees in recent months. TikTok told Sky News: "We strongly reject these baseless and inaccurate claims. "We have made ongoing enhancements to our safety technologies and content moderation, which are borne out by the facts: a record rate of violative content removed by automated technology (91%) and record volume of violative content removed in under 24 hours (95%)." #tiktok #skynews SUBSCRIBE to our YouTube channel for more videos: http://www.youtube.com/skynews Follow us on Twitter: https://twitter.com/skynews Like us on Facebook: https://www.facebook.com/skynews Follow us on Instagram: https://www.instagram.com/skynews Follow us on TikTok: https://www.tiktok.com/@skynews For more content go to http://news.sky.com and download our apps: Apple https://itunes.apple.com/gb/app/sky-news/id316391924?mt=8 Android https://play.google.com/store/apps/details?id=com.bskyb.skynews.android&hl=en_GB Sky News Daily podcast is available for free here: https://podfollow.com/skynewsdaily/ To enquire about licensing Sky News content, you can find more information here: https://news.sky.com/info/library-sales
