Affected employees were reportedly told of the impending layoffs in an internal memo Tuesday night sent by TikTok’s head of operations Adam Presser, and Zenia Mucha, the company’s chief brand and communications officer.

The number of employees affected has not yet been revealed, though The Information reported that a “large percentage” could be let go.

A spokesperson for TikTok confirmed to the Associated Press earlier this year that the company had laid off roughly 60 workers in its advertising and sales department.
