Twenty-three people in Northern Ireland are facing redundancy after one of the UK's biggest parcel delivery firms went into administration.
Unions have demanded urgent talks with Business Secretary Vince Cable after City Link called in administrators.
The company announced the move on Christmas Day after years of "substantial losses".
It comes as a shattering blow to the firm's 2,727 staff, including 23 based in Co Antrim.
Operations have been suspended at all its depots until Monday, when customers and those expecting deliveries will be able to collect their parcels.
One City Link worker, who wished to remain anonymous, called the situation "utterly disgraceful".
"I worked on Christmas Eve with no warning this would happen; I found out from the news," he told the BBC.
"I am so furious with what has happened, I have no idea what I'll do."
A union claimed the timing of the announcement was "disgraceful".
The RMT said it believed there may have been "more cynical motives" behind the decision to "delay" the announcement until Christmas Day and demanded an investigation.
It said it had been told City Link was in administration on Christmas Eve, a fact neither the company nor the administrators were prepared to confirm publicly until the following day.
