About

Provided by Haynes and Boone, LLP

Our lawyers handle complex, high-stakes labor and employment matters facing management teams across the U.S., with a keen understanding of the need to balance legal options against company strategy. We also handle high-level executive compensation issues for public companies, hedge funds and private equity firms. Similarly, we play an integral role in major transactions, such as mergers and acquisitions, providing advice and counsel, and drafting employment-related provisions or agreements.

We have extensive experience litigating and counseling clients on wage/hour issues; labor/management relations and arbitration; unfair competition/trade secrets; advanced-leave issues; OSHA/workplace disasters; ERISA claims; immigration; and pandemic-related issues.

Our group appeared across the country in wage/hour class actions and throughout Texas in injunctive relief proceedings involving unfair competition and trade secrets. We successfully tried cases involving multimillion-dollar claims and achieved favorable and precedent-setting appellate court rulings. We also assisted clients facing aggressive regulatory enforcement by such agencies as the EEOC, NLRB and Department of Labor. We have been national OSHA counsel for one of the largest U.S. retailers for more than a decade.

Our team represents domestic and international businesses across a range of industries, including energy, technology, retail, healthcare, banking, financial services, real estate, manufacturing, and construction.
