The initiation of a grievance shall not be construed as reflecting on a volunteer's standing, performance or desirability as a volunteer. ACTION intends that each supervisor and sponsor, as well as ACTION and its employees, maintain a healthy atmosphere in which a volunteer can speak freely and have frank discussions of problems. A volunteer who initiates a grievance shall not as a result of such an action be subjected to restraint, interference, coercion, discrimination or reprisal.
