I'm sorry, stiglet, but your faith in peoples ability to see the future is amazing.
you should know what hours and lifestyle the job entailed before you started; if you are not suited you shouldn't have become a commercial pilot.
How the friggin hell are you supposed to know what will happen to you BEFORE you start working? Nobody has magic powers to see into the future and know beforehand what rules and regulations may or may not be in place when you actually go to work. This is just rubbish. Like tarot or whatever. Arghh.
