Union leaders are to meet with Pfizer management in Cork on Monday to discuss job losses at the company.
Yesterday workers there were told that 65 positions are to be axed at the Pfizer's main plant in Ringaskiddy, while up to five hundred other jobs are at risk in Little Island and Loughbeg.
The Technical Engineering and Electrical Union, which represents over one hundred and thirty staff at Pfizer, will hold discussions with management at all three plants on Monday.
The union says the purpose of the meetings is to give management an opportunity to advise it on the implications of the announcement.
