Marc J. Siegel is a sought-after labor and employment arbitrator and mediator able to quickly understand both sides of complex issues. He has advanced negotiation expertise, business acumen, and an innate ability to foster calm and easily relate to and empathize with all parties.


Marc’s ability to understand competing perspectives has been honed by practicing labor and employment law in Chicago his entire career, first for seven years with Laner Muchin, a preeminent mid-size Chicago management-side labor and employment firm.

He advised employers on all types of employment matters, including conducting audits of employment practices, running organizing campaigns, handling collective bargaining, and defending numerous employment cases before the EEOC and unfair labor practices before the NLRB.

He then co-founded Caffarelli & Siegel, a boutique employee-side labor and employment firm, and served as managing partner. Mr. Siegel went on to found Siegel & Dolan, an employee-side labor and employment firm, where he serves as managing partner.

After nearly 20 years counseling and advising hourly employees, CEOs, physicians, university faculty, and other professionals, he has highly developed abilities to relate to and empathize with parties of all backgrounds and experiences. He has successfully negotiated six-figure severance packages countless times, as well as favorable outcomes in wage and hour disputes, even when tensions and anxieties are high.

In addition to reviewing the mediation statements, he speaks with both sides, and is very prepared to address key issues at mediation. Marc has a very mellow style that puts everyone at ease.
