Everyone should have to consider the source of whatever is written and make our own choices about what to believe. That is free speech. Including what I write. I do not need you to question me. If care anything about education, question John.

I did say that teachers, past or present or budding, are by and large fit intellectually to decide the true situation according to what you and others have posted re said school.But in my view, the kind of person who believes what John has posted wouldn't be an asset to your school in any case.That is just my view, which of course I'm entitled to. Despite that,I have no regrets letting others make up their own minds re said school, even if they are diametrically opposite to mine. Of course, I have no hidden agenda re said matter, as I've no intention of teaching in Ethiopia, and never will have.
That said, my take is that supply and demand likely dictated why said school chose to appoint John, ie Hobson's choice. What's more, I think that everyone who makes mistakes should suffer the consequences thereof, employers and employees alike. Employers aren't high and mighty compared to employees, in my opinion. Actually, I suspect that there were faults on both sides in John's particular situation. At the end of the day, I ask myself why he felt it necessary to make so much trouble for the school. Either he's very vindictive or he genuinely feels he has been mistreated by his employer, rightly or wrongly.
It's good that you have posted your side of the story to counter his. But I also feel that this forum shouldn't be berated for having posted his side in the first place - there are too many wimpy forums for EFL teachers on the net! Long may this forum continue to operate in the same way it has up to now!
