Most pilots and most employees DO have a problem with Bonds.
After all a Bond is nothing more than an acknowledgement from the company that they are not paying Industry Standard pay rates and will use artificial methods to keep you in place.
Look at the concept, we are going to keep you in Bondage. How is that legal?
BA, LH, AA, DL and QF don't have Bonds. They must pay Industry Standard pay so hence no one leaves the company.
As a pilot Widebody you should be very much against a Bond of any kind.
