No!!!!If he does actually go to panel, they may "ice" him by continually postponing his case until the last minute. This is designed to torment him. I've seen it.
They may, after "icing" him for three days, settle it in the hallway so it doesn't appear on the record.
Take the offer of reinstatement with no back pay.
This event will forever mold your and his thoughts and opinions of the company.
From this point forward DO NOT do the company any favors and cover your A##.
Never!!
