Just for the record: I can't remember saying that I don't want to do 12 hour shifts. I just referred to the FAA rule that FAA dispatchers shouldn't be rostered for shifts longer than 10 hours. And if you would be unionised then you might have to adhere to similar rules. That's all.
But if some of you lack the capacity to read a post and then just start foreigner-bashing, then fine. Just remember that PPrune is an international forum. Keep it cool and professional, including you language. It doesn't look very good on us if someone finds out who we're working for.
