you could also sell him on yourself with how you have saved him some money. Have you set up fuel programs, re-negotiated training contracts with the training provider, helped with the insurance. These are all areas where money can be saved and the owner might not see it. Let him know and if you do get let go you can always cancel whatever agreements you set up or just not tell anyone. I am sure FSI/CAE will be glad to charge the new guy full price. Be professional, but most importantly get another job ASAP.
