Nice in Europe!
NOT talking specifically about aviation - The standard working week in the Middle-East is 48 hours - sometimes 45!
And back in UK a few years ago, I was with a manufacturing company whose staff were cut to "no overtime" ("recession") and many were struggling to pay their mortgage. I was a "company hero" when I designed a bit of kit that got a bit BT order and sudenly it was "no restriction on overtime"!
Compulsory overtime is a different story. I've probably put in some 60 or 70 hours this week (no overtime pay!) at my own choice, to try to get some things off the ground, but I didn't have to
Specifically Aviation - I'd certainly not want to think that the crew of the aircraft that I was in as a pax (sleeping, to catch up on my lost rest!) were tired from excessive hours. If I'm over-tired, the worst thing that can happen is that I run off the road driving back from a customer site (okay, maybe I drive off through on-coming traffic and take out a couple of others - not good) but a tired flight crew is something we don't want to even think about.
When mass-safety is concerned, you should be able to dictate when you are tired and when you are not!
(my riyal's worth!)
