For criminal lawyers it's the sexiest job in town, but the esteemed Office of the Director of Public Prosecutions is heaving with overworked staff.

And relations between the bewigged and wigless tip between passive aggression and outright hostility.

Several staff have come forward to report instances of bullying and weak management at the DPP since Fairfax Media reported last week that the director, Lloyd Babb, had circulated a memo on workplace harassment. It is understood that the managing lawyer at a regional DPP office has resigned following an investigation by the public sector workplace consultancy GVK.

About 20 solicitors had earlier threatened to resign unless action was taken against the managing lawyer.

Allegations of bullying have also been levelled at crown prosecutors and their junior equivalent, trial advocates, at the Sydney office.
