The new owners of Clerys department store have refused to meet the minister tasked with examining the closure of the shop.
Ged Nash had written to Natrium seeking an urgent meeting, to discuss the loss of around 400 jobs at the Dublin landmark.
The Super Junior Minister for Jobs is due to present a report on the matter to the Taoiseach this week.
However his department has confirmed that, despite initially agreeing to a meeting, Natrium now says it will not be available until after next week.
Clerys ceased trading on June 12th, following the appointment of Kieran Wallace and Eamonn Richardson of KPMG as joint liquidators of OCS Operations Limited, trading as Clerys.
In a statement last month, Natrium said it wants to support 1,000 jobs through the planning and refurbishment of the building over a two-year period.
It adds that "a predominantly retail-led development encompassing other commercial uses, subject to the planning process, will generate a minimum of 1,700 new sustainable long-term jobs in Dublin City Centre."
Former Clerys workers have continued to protest over the sudden closure, and thousands of signatures have been gathered in support of their position.
