Pannone has put more than 100 people on notice of redundancy since the firm agreed to press ahead with a tie-up with Australian-listed Slater & Gordon.
While Pannone refused to confirm the figures, insiders indicated that a consultation involving over 100 staff is underway with a completion deadline of the 31 January.
The Australian-listed firm said it would acquire 400 staff as part of the buy-out of the consume business while 50 lawyers and staff would transfer to spin-off firm Pannone Corporate.
According to The Lawyer’s UK200 figures, Pannone had a total of 587 at the end of the 2012/13 financial year, leaving 137 jobs unaccounted for.
Slater & Gordon chief executive Neil Kinsella has told The Lawyer that Pannone managing partner Emma Holt and financial director Anthony Clare will be key to the management of Slater & Gordon going forward.
Holt will concentrate on post-merger integration, with the goal of bringing all staff from all Slater & Gordon’s recent acquisitions onto one platform by March 2015.
The latest acquisition by S&G, that of personal injury firm Fentons, was unveiled in August (21 August 2013).
