Oi Rocket Surgeon,
You forgot to mention that in the case of the two companies that offer "genuine" equal time rosters that the "on" time is usually in some sh*t hole, away from your family and whatever quantifies your lifestyle.
So the Esso guys fly a lot. Is that a bad thing is it? They spend their off days (and yes, also their night standby days), polishing their hogs, boats and whatever.
How did we get so far off topic?
