You can get your crew message when you show up to your published rostered duty, as required by the CAD so you can plan adequate rest. Do that and you will see how few roster changes you get.
Keep in mind guys, if you ever find yourself on the stand and your performance is under question, you will not be able to say "I was tired" as a defense. The company has gone to great lengths to isolate themselves legally while retaining productivity. That is all that FRMS is, a way for the company to pass the buck on to you if they roster you to the limits. That is why it is so important to make a paper trail for any rostering abuses. They are counting on us to not bother with forms, that is why they make them tedious to fill out.
Make no mistake, if you operate an aircraft while "fatigued", you will be held criminally responsible and there is nothing that any organization or lawyer can do. It is now the same as driving drunk, so you should not use "I was tired" as a defense as much as you would not use "I was drunk" to remove your blame.
And for those with trouble reading the fine print, that means whinging about being tired in the cockpit. When they pull the CVR, if you are on there complaining about how tired you are after a !!!!ty roster, this is the same as bragging that being at the bar doing shooters right before departure was a bad idea.
So be careful boys and girls, the framework has changed - fatigue is still just as much, if not more, of a problem. But the consequences are now aimed at you, there is no more "shared responsibility".
