Electrics retail chain Comet is preparing to close between 30 and 40 stores by the end of the month, according to reports.
Administrators have so far announced 330 redundancies at the company but there have been no job losses among shop staff and all the chain's 236 stores remain open.
The reported closures could threaten the livelihoods of up to 1,000 frontline staff.
It has also been suggested that Deloitte, who was appointed administrator when the chain collapsed earlier this month, is preparing to close down the retailer's home delivery operation, putting a further 500 employees at risk.
The stores which do not close are expected to continue trading over Christmas.
