Biography

David Rosenthal is a partner in the firm’s Labor and Employment group. He primarily represents employers in state and federal litigation, in court and before administrative agencies in the full range of employment disputes. David also counsels employers on compliance with state and federal regulations that govern their relationships with their employees.

What do you focus on?

Protecting employers from the misuse of their confidential information and trade secrets by former employees is one of the primary focuses of my litigation practice. I focus on responding quickly and successfully to such threats by obtaining injunctions to prevent the misappropriation of valuable information and unfair competition. In some cases, I have been called upon to represent talented individuals in lift out situations, allowing them to compete fairly using their personal skills and know-how in more suitable employment settings.

Employment discrimination litigation, defending wage and hour class action matters and contesting whistleblower claims—all on behalf of employers—comprise the balance of my litigation practice. A persuasive advocate for my clients, I have a long track record of success in defeating such claims, by trying cases to judgment or achieving resolutions on very favorable terms.

Dispute avoidance is also a large part of my practice. Assisting clients with legally compliant policies and procedures, providing practical advice before the dispute escalates, and using practiced, successful mediation techniques have contributed to many advantageous resolutions of potentially damaging disputes.

I view my job as being a problem solver. I make my clients’ jobs easier by helping them with what are often emotionally charged, and legally complex, decisions about employees and resolving them practically and efficiently. Many clients have told me they want an employment lawyer who tells them what they can do, not what they can’t do. I try to be that person.
