You're absolutely right. The way things are is that private schools can attract the best teachers by paying them to teach while public schools are paying premiums for sub-par employees to micro-manage. The public education system is aborting itself. It probably should be done away with.
I'd prefer not to support with tax dollars any institution that pays administrators to monitor 'laborers' based on social media. Whomever was on the other end of the phone line should've had the brains to hang up the phone, but like a good sheep, they 'did their job' to the letter. The man was suspended over a rumor no one should fear losing their job over a rumor.
But, you're right in that ranting on the internet isn't going to change a thing.
