Overview
Jack is co-leader of Dorsey’s firm-wide Labor & Employment practice group with a diverse practice encompassing a wide range of employment and labor issues. As an advisor, Jack counsels C-suite executives, owners of closely held and small businesses, human resources leaders, and in-house lawyers on complex questions, including: medical and disability accommodation and leave issues; non-competition, non-solicitation, and trade-secret obligations; responding to unionization efforts and managing union relationships; and assessing high-risk hiring, discipline, and termination decisions. As a litigator, Jack prosecutes and defends actions to protect clients’ trade secrets and ensure compliance with their contract rights in non-competition and non-solicitation matters. He also defends against alleged violations of state and federal employment laws and represents employers during investigations and proceedings brought by or before the Occupational Safety and Health Administration, the Equal Employment Opportunity Commission, the National Labor Relations Board, and other federal and state agencies.
Jack’s advice to clients is informed and strengthened by his own professional experience as a manager, as he served as a newsroom leader and editor during his first career as a journalist – and so knows first-hand the challenges and rewards of effectively hiring, training, and managing employees.
