California Employment Law

Overview Experience Press Room


California is well known for its continually evolving labor and employment laws and compliance requirements, which are often broader than their federal counterparts, presenting myriad challenges for companies around the world with operations in the state. Our California Employment Law Group has distinguished itself as one of the top practices in the U.S., focusing on the unique requirements for doing business in California.

The group handles lawsuits in state and federal court, wage and hour class actions, arbitrations and administrative agency complaints, common law and contract claims. We also offer workplace counseling as well as workforce and management training and customized compliance solutions for the unique issues that arise under California law. Indeed, our regional experience and international platform position us as the go-to California labor and employment practice for businesses from all over the world.

Our lawyers are recognized as leaders in the field, with Chambers USA praising Anthony Oncidi, co-head of the California Employment Law Group as "an experienced and seasoned attorney who offers advice with great judgment". Additionally, The Legal 500 United States lauds Mark Theodore, co-head of the Labor-Management Relations Group, as a lawyer who “knows the subject matters backwards and forwards” and “is astute in acting before the NLRB.”

We were recently honored as one of the top three firms nationwide for Labor & Employment Litigation by The American Lawyer, where it was noted that clients retain Proskauer when "the company's reputation is on the line" and "managing the public face of litigation" is of utmost importance. Indeed, our high-profile matters involve sensitive, complex situations with sweeping ramifications that impact both our clients and their industries.
