Staff will find out what Cardinal Health's decision is today.
Hundreds of job losses could be looming for staff at an Offaly medical manufacturing plant.
Cardinal Health, based in the Sragh Business Park in Tullamore, is calling all staff to a meeting today.
SIPTU says the union has been invited to a shop stewards' meeting in advance of the company's meeting with staff.
Cardinal Health employs around 350 staff at the Offaly facility, which has been in operation for close to 40 years.
Offaly County Council Cathaoirleach Tony McCormack says there will be wide reaching consequences:
Independent Laois Offaly TD, Carol Nolan says: "This is devastating news and one that demands all agencies of state to respond as part of a concerted and unified effort to save these jobs"
"My heart goes out to the workers and their families at what must be a truly unnerving time." added Deputy Nolan.
