In another sign of the hard times facing the legal industry, particularly in real estate-heavy south Florida, two law firms — Holland & Knight and Shutts & Bowen — have laid off nonlawyer staffers.

On a day that could be dubbed “Black Friday” in south Florida legal circles, Holland & Knight, one of Florida’s largest and most venerable firms with 1,150 lawyers, laid off 70 staffers on May 16, including legal secretaries, information technology and accounting staff. No lawyers were laid off.
