This sounds to me like unfair termination. Did your hubby get the compensation?
IMO, he should escalate and voice out the unfair treatment he's been getting and a clear request for reinstatement or "redressing of grievances". If the CEO is someone fair, he will loook into it. BUTTTT if he is another kind just like the botak... then tell your hubby to give up this co..
Maybe another option is to raise this to MOM to complain about that Botak and also to seek compensation.
