SIPTU will meet with Glanbia management today to discuss the company's plan to close its plant in Inch, Co Wexford.
The move would make 50 workers redundant.
SIPTU, the union which represents the staff, saiod the focus of the meeting will be on saving the jobs.
Glanbia made the announcement late last Thursday evening that it intended to close the Wexford factory following an agreement to sell the Yoplait Ireland yoghurt business for €18m.
Glanbia has held the Irish franchise for Yoplait for the past 40 years, and introduced the popular French brand to Ireland in the early 1970s.
It is selling the country franchise to Yoplait’s ultimate owner, US food group General Mills, which has recently also bought the regional franchises for Yoplait in Britain and Canada.
However, the Kilkenny-headquartered group will still distribute Yoplait products in Ireland, on behalf of General Mills.
