Why do parties go to arbitration instead of to court?

Generally, arbitration is perceived as a less expensive and quicker method than litigation of resolving labor/management disputes. Especially in a setting where unresolved disputes may fester and impede productivity, an efficient way of settling disagreements is imperative. The parties also have the opportunity to select an experienced labor arbitrator who is familiar with industry standards and the peculiarities of interpreting a collectively-bargained contract, rather than have their case heard by a judge or jury who may be unfamiliar with the labor-management context.
