The future of THA Group is in question after the company called in administrators on Friday.
C&IT has obtained a statement from a former employee of THA, who received confirmation of the situation on Friday.
THA was unavailable to provide official comment this morning, but a statement is expected shortly.
The agency has already made some 50-plus redundancies this year, which THA Group chairman Kevin Ingram said was in response to "a major decrease" in client business, and last month put its Belgian business into administration.
