Dave handled a wide range of labor and employment matters for clients in the health care, educational, social services, financial services and commercial fields. He advised clients on the full range of issues facing employers, including performance management, discipline and discharge, wage hour matters, and leaves of absence.

A significant portion of Dave’s practice involved the representation of employers in dealing with the range of union-related issues, from union organizing and National Labor Relations Board proceedings, to union contract negotiations and operations under collective bargaining contracts application, and labor union grievance arbitrations. Dave also had experience in complex business immigration matters.

Dave served as the firm’s own employment practices compliance counsel, and played a major role in the firm’s own performance evaluations and performance management of its associate lawyers.
