There are fears for the future of around 50 jobs in Belfast at security cash-in-transit firm Brinks amid claims the operation is set to close.
The security firm restocks cash points across a range of businesses in Northern Ireland, including Ulster Bank.
The firm's base is at Duncrue Road in the city.
Brinks confirmed in February that it was to cease operations in the Republic with the loss of 200 jobs.
One source told the Belfast Telegraph that while there had been talk of finding a new buyer for its Northern Ireland business, workers would get an update next week on the future of the firm.
He said he expected staff would be told that jobs will be lost and the site could close.
Brinks employs a range of workers here including drivers, administration staff, cash-processors and control staff.
Following the 200 jobs losses in Dublin, Cork and Galway, it was reported the company was negotiating the sale of its operation north of the border.
It said it would continue to operate here and services to local customers wouldn't be affected.
Trade union Siptu reacted with anger to February's decision to close the Republic of Ireland wing of the business after it had reached a restructuring deal with the company to safeguard jobs.
Brinks said at the time that the cash-in-transit market in the Republic had not been profitable in recent years and it did not see opportunities for growth.
Siptu organiser Brendan Carr said staff were extremely disappointed by the move in light of the restructuring deal.
"Unfortunately, despite the sacrifices of its workforce and their willingness to adapt to the company's demands it has still decided to end its operations," Mr Carr said.
"These jobs have been endangered, in part, due to the operation of low cost employers in the security industry. The workers are extremely disappointed by this announcement."
Brinks was Ireland's third largest cash-in-transit carrier, with a market share in excess of 20%. It had warned investors at the end of last year that Ireland was "a tough environment".
Brinks is an American security and protection company headquarted outside Richmond in Virginia.
Its brand and reputation span the globe and its network serves customers in more than 100 countries and employs around 70,000 people. In 2012 it agreed to sell its cash-in-transit operations in Germany and Poland.
No one from Brinks was available for comment.
