Yes, a number of our pilots, mostly Captains, the F/Os want the hours, work a 75% or 50% roster. I'm afraid I can't quote the terms, but understand it's 50% (75) of everything, pay, days off, pension, work days etc( simulator etc for trainers). Don't know where leave comes in to this. I don't know whether you can get employed on these terms or if you have you work for them already.
Not much help, but any helps I hope.
