Firm Background

Lewis Roca Rothgerber's employment lawyers provide clients with representation in employment litigation and administrative proceedings, as well as counseling across the full range of the human resources spectrum. The group's strengths for effectively serving clients are the lawyer's backgrounds and substantive labor and employment knowledge. The core group of lawyers have exclusively practiced in the employment field, defending employers at all levels on every type of labor and employment claim.

We defend employers in state and federal courts against wrongful termination suits and individual or class actions under the civil rights laws, the ADEA, ERISA, FMLA and other employment statutes. We routinely represent employers before various regulatory agencies in discrimination, unfair labor practice, wage and hour, job safety and health matters and have provided counsel to management concerning problem-solving, legal compliance, union avoidance and, increasingly, alternative dispute resolution. For employers with bargaining units, we also provide advice and representation in collective bargaining, concerted activity, arbitration and other labor-management matters. Whether the case implicates political issues, sensitive psychological issues, or even criminal claims, the employment team is equipped to assist the client with creative strategies to reach the most effective outcome possible.
