Around 680 staff have been made redundant at window and door manufacturer and seller Safestyle.
The business had gone into administration and the GMB union had expected up to 600 job losses.
But on Monday, administrators Interpath Advisory were appointed and said the number was around 680 workers.
Staff were unexpectedly texted to “down tools” on Friday evening at the Bradford, Yorkshire headquartered company.
Before the weekend, on Friday, the Safestyle board filed a notice of intention to appoint administrators and said the company could not continue trading as a going concern.
Trading in company shares on Friday morning was temporarily suspended, “pending clarification of the company’s financial position”, a regulatory notice said.
Additional funds had been sought but on Thursday the company said it did not expect to be in receipt of capital or new financing.
