Every company with more than just a few employees needs a clear procedure for reporting and resolving grievances.
The procedure should provide for the situation where the supervisor is the subject of the grievance - another person should be designated to handle the grievance in such a case.
An effective grievance procedure can be a useful tool in helping an employer avoid morale problems among employees, which may also make the need for a union seem less compelling for many employees.
It can also be an important part of an alternative dispute resolution system.
Keep grievance records in a separate grievance and investigation file.
