All 22 employees of the UK paper's Irish edition have been asked to be available over the next two weeks to be individually informed of the intentions of management, with the possibility of being offered “other positions”.
Staff will receive full pay for the next three months.
There are also 10 part-time staff as well as columnists, including hurling legend DJ Carey.
Despite speculation that the paper would be rebranded, employees have not been informed about plans to launch a new title, such as the rumoured ‘Sun on Sunday'.
On Friday, letters were sent out informing employees they were under threat of redundancy.
The Irish title, which is edited by Geoffrey Frazer, from Banbridge, had a circulation of around 120,000 in recent months.
