Thinking about putting this in my signature:
Do not pick up your phone when you are called by a blocked or an Irish number while on OFF days. Crewcontrol rarely or never leaves messages on your voicemail. Chances are if someone else is calling you they will leave a message on your voicemail. You don't really have to worry about people not being able to reach you in this case.
In other news. FO who just recentely upgraded to captain returned to major European base bypassing several people on the "list".
