So having worked in public services my whole career, I am in two minds.
On one hand, legitimate complaints are an important part of accountability.
On the other hand, in this digital age there are two problems.
Firstly it can result in a disproportionate amount of limited resources going on a handful of vexatious complainants. Some people are just genuinely a pain in the arse, and time taken dealing with them is simply time not taken actually sorting things out for everyone.
Secondly there can be a "pitchfork mob" effect where things get out of hand and people wind each other up. This can verge into slander/libel amd can be very damaging.
In the case of schools, and the increasing incidence of special needs diagnoses, we are at a juncture where we have to decide on what basis we allocate resources. Are they needs-based (ie school assessed needs) or diagnosis-based?
The problem with diagnosis based is you can complain and lobby the school to your heart's content but if it's not bringing in resources, its just taking from otger children.
And I'm sorry but I have friends who are very entitled and sharp-elbowed about everything and their expectations are out of synch with reality.
So I think vexatious complainants are a real issue that needs a solution before we lose some of our most dedicated and caring public servants. To.all.of our detriment.
