After seeing all of the mail generated by this discussion I have been sitting patiently waiting for someone to bring up the obvious. Just because the Government allows a shop to be opened for 24 hours a day doesn't mean that a clerk has to work 24 hours a day. The time allowed by law is just a legal thing,the time that we as pilots work is a contractual thing, so lets get our heads out of our a*** and decide how much work we are willing to do and for how much money.
Many years ago when I flew sightseeing in NYC the "heavy equipment operators union" (guys who drove the cranes and big cats) tried to organize helicopter pilots. They were earning about $100 per hour and I was on $15, but the comment from so many of my workmates was "I'm a pilot not a construction worker" it sounded stupid then and it sounds stupid now. Please guys let's stick together and earn a salary that equates with our responsibility. If you feel fatiqued don't work but if it is just a matter of money let's negotiate.
