Senior US-based executives of ICT Eurotel are due in Belmullet, Co Mayo, on Tuesday amid increasing fears for the future of the company's local operation which employs up to 80 full-time and 50 part-time workers.
Meanwhile, Oatfields sweet factory in Letterkenny, Co Donegal, announced 14 jobs are to go.
Attributing this and other industrial job losses to Fianna Fáil for its "sloppy handling of the economy", Fine Gael TD Joe McHugh said this kind of downsizing could result in massive job losses.
"The county is lacking in high-tech, high-value jobs and in the current climate we will suffer," he said.
There were similar concerns yesterday in Co Mayo concerning the ICT plant, which had located its quality verification centre in Belmullet six years ago. The future of the operation, the town's largest employer, is now uncertain.
Unconfirmed reports suggest that the company is on the verge of a major downsizing operation, with as many as half of the Mayo jobs going to India, where hourly operating costs are said to be one-fifth of those in Ireland.
The weakness of the dollar against the euro is said to be a contributory factor to the firm's problems in Ireland.
The ICT group employs about 5,000 people worldwide and operates customer contact centres in Athlone and Dublin.
The company, which has been supported by Údarás na Gaeltachta, is based in Belmullet industrial estate. The authority has been engaged in extensive discussions with ICT over recent weeks to determine the exact problems facing the company and to see if it can help.
Local Údarás member Ian McAndrew refused to discuss the issue last evening in advance of the briefing by management that is planned for Tuesday.
However, it is understood that ICT's mind may be made up on the relocation issue despite the offer of fresh financial incentives from the Gaeltacht authority for them to remain here.
Mayo TD Michael Ring, who is Fine Gael spokesman on rural, community and gaeltacht affairs, demanded last evening that the workers at the plant be informed by the company and Údarás as to exactly what was happening.
"The workers and their families need clarity," Mr Ring said. "There has been a lot of speculation in the media in the past few days. From my own point of view, I hope the company is going to stay in Belmullet."
No sales calls are made from the Belmullet plant. Digital recordings of all sales transactions made at ICT's European and US centres are transmitted to Belmullet for verification.
