The author identifies ten precepts that although are now uniformly accepted in private grievance arbitration, were once vigorously disputed. Among them is the notion that an employee should obey now and grieve later, that new evidence and new contentions should not be introduced at arbitration. However, now that private grievance arbitration is an established, even stultified process, variations such as local expedited arbitration and per curiam opinions should be considered, and parties should direct “little cases” to less cumbersome procedures. All grievances should not necessarily be treated in the same manner and subjected to identical procedures.
