If the owner is a business man he will listen if he not shut up.
The danger in keeping all this to your self is if the boss finds out he may clean house, if he can without hurting himself,figuring all are guilty. I am a boss and if I got wind of this I would wonder why no other employee told me about it. I would have a hard time trusting anybody in the shop again and clean house as soon as I could. I need to be able to trust the people that work for me, if i can not they are history.
