While the union is fairly strong, and in my opinion slowly getting stronger there is no agreement for that.
What you would normally get is a night flight into rest day before days off (so arguably an early as a rest day is not a day off). You are ensured at least 2 of your DO blocks do not have a start after 8am although they try to keep the earlies after DO's as low as poss.
Union agreement is for max 800hrs. If you are offered A320 then expect eventually to be CCQ with the A330, this is however very unpopular with the troops because of the way rostering roster the two together !
It's far from being a bad outfit but it has become just a stepping stone to better things with all the BA/VS recruitment going on. Just my humble opinion.
VP has it spot on there. A good company, good, friendly management (in the most), but not the best outfit around and now a very long time to command.
