Workers at the ICT Europe telesales centre in Belmullet, Co Mayo, say they have still not been given any indication of the company's plans. There have been fears of job losses at the company, which employs 140 people.
Workers had been waiting to be briefed by senior company executives, who had flown in from the US and the UK.
There are fears that up to half of the workforce at the centre, the town's largest employer, may be made redundant. Local management is refusing to comment on rumoured job losses.
