In labor-management disputes there is a fairly standard distinction between mediators (who tend not to arbitrate, and are usually government employees) and arbitrators (who frequently have no experience in mediation, and are mostly part-time practitioners, often with an academic income base.) A number of those listed here have served extensively in both capacities, and have a correspondingly broad perspective. (One, Hobgood, is not currently employed as a neutral; but his all-but-unique volume of experience as a neutral was a primary reason he was asked to fill an unusually sensitive management post.)
