Irish-based staff at video-sharing platform TikTok have been told that they will be impacted by job cuts.
It is not yet known how many workers will be laid off and TikTok has declined to comment.
Almost 3,000 staff are employed at the company's Irish operation.
The Department of Enterprise said it has not received a collective redundancy notification from TikTok.
Job cuts of 30 or more would require such a notification.
Reuters has reported that TikTok is laying off staff globally at its trust and safety unit which handles content moderation, as part of a restructuring.
According to the report, Adam Presser, operations head of the app who also oversees the unit, sent a memo out to staff today notifying them of the move.
The layoffs began on the same day for teams in Asia and Europe, Middle East and Africa, according to sources.
The move comes as TikTok's fate remains up in the air. The popular short video app used by nearly half of all Americans went dark briefly last month, before a law took effect on 19 January that required its Chinese owner ByteDance either to sell it on national security grounds or face a ban.
In January last year, TikTok CEO Shou Chew testified before Congress alongside Meta chief Mark Zuckerberg and other tech and media heads in a hearing where politicians accused the companies of failing to protect children from escalating threats of sexual predation on their platforms.
Replying to questions from Republican Senator Lindsey Graham, TikTok's CEO had said that the company would spend more than $2 billion on trust and safety efforts.
In October last year, the company laid off hundreds of employees from its global workforce, including a large number of staff in Malaysia as it shifts focus towards a greater use of AI in content moderation.
TikTok says it has 40,000 trust and safety professionals worldwide.
