Whilst the poorly considered, ill timed and inappropriate nature of the Cllr comment appears to be the issue under examination in the quest for advice, I would suggest the Cllr comments are merely the SYMPTOM rather than the root cause of the more fundamental problem being portrayed
To effectively address a problem, it is necessary to recognise the relationship between root cause and symptom.
Symptoms are often what draw our attention to a problem (the Cllr comment is the symptom) but resolving them alone does not lead to lasting solutions. Instead, symptoms simply serve as indicators, guiding us toward the deeper, underlying issues—the root causes.
The root cause of the problem as described is two fold.
(1) a chair who appears to lack an adequate understanding of the context of the APM and who seeks to exert excessive and inappropriate influence over other Cllrs (“…made Cllrs and the clerk sit at the front of the hall in a line of chairs…”) and,
(2) Cllrs that lack the knowledge and/or confidence to TELL the chair that they will attend the APM (if they choose to) and sit (if they want to) and speak (if they wish to) entirely at their own discretion rather than at the chair’s direction
I would consider the greater, and potentially more sustained and damaging, issue to be that of chair behaviour. Fix that and the other might not of happened at all….
