3,000 staff employed by Facebook in Ireland are expected to find out this morning if their jobs are cut.
Meta, which owns Facebook, Instagram and Whatsapp, is reportedly due to make an announcement at 11 am Irish time.
The company will cut thousands of positions from its global workforce of over 85,000 people.
It was reported in September that Meta was planning to cut expenses by at least 10 per cent, in part through staff reductions.
Technology Correspondent Jess Kelly says Mark Zukerberg has taken full responsibility for the difficult position the company finds itself in;
"Mark Zuckerburg told hundreds of executives on Tuesday that he was responsible for the company's missteps, he had over-optimism about the growth that led to overstaffing."
It comes after Twitter announced widespread job cuts, reportedly affecting over half of its workforce in Dublin. While online payments company Stripe also told employees of significant layoffs.
