Sure, I'll give you a few.
I personally have, throughout my career, dealt with complaints and grievances. I've dealt with them as a front-line manager in an institution, at the second level at regional headquarters, and at national headquarters when I was in the role of senior deputy commissioner. Here are some examples of frivolous grievances.
An individual complains about not getting access to the doctor in a timely way. We go back; we analyze that; we determine that, yes, there probably could have been something that could have been done differently; and we schedule that individual for the next time the doctor comes in. So for all intents and purposes the issue is dealt with.
The way the law is currently written, that individual, even though the issue has now been resolved, can still file a grievance and just complain about the fact that it wasn't resolved in a timely way by our own admission and carry it on to the next several levels in the grievance system. That type of grievance serves no purpose at all because the issue brought forward was identified as being a shortcoming by staff and was rectified, but now the offender is using the opportunity within the legislation and the policy to continue to just push a point through the various levels, and each level requires a response.
