Omar: Don't pick up your phone when you are off duty if you can't identify the number or see it's an Irish one. That's what practically any Brookfielder in my base does.
So true, I once answered and because I said no to work a day off (was at a wedding), I was given 5 standby days on my next duty week!! changed from a previous 4 days flying out of 5, so now I just don't answer on my days off, foreign number or with held. They only have themselves to blame.
