A government school has an enormous advantage over private schools in that it’s free at the point of use. You can be a lot worse than the competition if the competition is expensive and you’re paid for by tax money.
It has given rise to a bargaining mentality.
I think I see your point of view, but IMO that is too narrow a definition of "stakeholder".
One of the more commonly-accepted definitions of "stakeholder", at least from a project-management standpoint, would be:
"an individual, group, or organization, who may affect, be affected by, or perceive itself to be affected by a decision, activity, or outcome of a project"
Even in my work, I tend to think of stakeholders as those who stand to lose or gain based on the outcome -- literally, those who have a stake in the outcome. Many of them are active participants, but not always.
Just my 2 cents... I might be far from typical in this viewpoint.
If a teacher's work email is anything like my email inbox at work, ~90% of emails just go away if ignored. The other ~10% email again if it's actually important.
Once your contacts are "trained" not to expect instant feedback to every email they send you, you can often get some actual work done.
