I have never heard of this kind of training

But I’ve never worked in the ‘corporate realm’ either. Not sure how one “teaches” humility to someone who is so full of themselves to begin with. Sounds like someone figured out a scam, ahem, a ‘unique training track’ and someone has taken the bait, I mean, bought the manual. I guess the best that can be said is that the company has some money to be spent and they found someone to take it. LOL Nothing like a good match.
