Jack Sullivan



Jack is an employment adviser and litigator in Dorsey’s Labor & Employment group, where he provides business leaders and human resource professionals with practical guidance through difficult compliance, managerial, and workforce decisions. Jack also advises management on union and labor-law issues. His 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. Jack works to resolve potential problems and disputes on terms that work best for his clients so they can focus on the needs of their business – and when matters can’t be resolved, is a creative and effective litigator who has represented clients in state and federal courts and private arbitrations across the country.
