It's not really enforceable outside Bahrain. You can forget about your leaving indeminity if you bail while under your bond, and may or may not have issues getting your last paycheque once you give notice (if you do).
It's more of a proffessional thing. It's a bit bad form to just disappear while bonded, and you certainly burn a few bridges. That being said there are several people that just have had enough and go, there isn't much GF can do if you have no plans of returning to the ME to work.
