Describe the grievance process and what it does for both the administration and the employee.

The term "grievance" is a term of art in labor and
employment law.  It applies to situations in which there is a labor union and a
collective bargaining agreement that provides for a mechanism with which to dispute a
management practice.  An arbitrator that is agreed upon by labor and management is
selected, and that person settles the dispute.  Because grievances are handled this way,
there is a fairly quick resolution by an unbiased outsider, which is much better for the
workplace than a protracted court battle.  Because there is consensus on whom will make
the decision, there is a perception of fairness in the
result.

Workplaces which do not have this process, those
without unions, might have some other dispute resolution process, but these are likely
to vary considerably from company to company.  However, the same considerations would
likely apply, a perception on the part of labor and management that disputes can be
resolved quickly and fairly.
