Blueberry, this behaviour you are so chuffed about would not be tolerated in any other sector than higher education. Employees of any other large business writing public letters complaining about an employee would be considered so unprofessional that it doesn't cross anyone's mind to do it.
There are internal procedures employees can use for grievances.
I'm astounded at the abusive way academics treat each other and it's extraordinary to see them do this in a setting where they are supposed to be influencing young people.
I've been working with academics for the past few years after decades in business and I am really surprised at the culture of public nastiness that exists. I have reached a point now, when discussing plans with colleagues about engagement with issues with faculty, that I have been warned so often that the people I have to meet with hate each other, I now just assume that they do.
There was bullying and disdain in business, but it is far easier to dismiss bullies in business and it is actually disapproved of rather than allowed to flourish.
So blueberry, your minimising of bullying doesn't surprise me at all, it's just indicative of the awful culture young people have to study in. I don't think you need to be proud to promote that here.
