The one thing that stuck out the most for me in this thread was the fact your friend told you about the confrontation in work/called him in. I know they held off for a while but surely if they are employing him this should be between them and him. For his own self worth, this should be the case.
You mention he never appplied for any jobs since getting this one. Firstly you have to give him credit for re-training and giving this a go. But now he's realised he hates the new job so maybe he feels stuck in this new sector as you say his prospects for employment from his old job are slim to none.
Is there any way he could look at other alternatives for retraining in the evenings perhaps? He needs to have some sort of hope for the future
Good luck and I hope it all works out for you.
