Interesting that the F/O has been stood down also. Admittedly, a week off when you're on the 777 is pretty standard these days anyway
but I fail to see any point in taking disciplinary action against them for being locked out.
I've also been subjected to the "Random Drug & Alcohol testing"... they tap you on the shoulder very close to departure and haul you off for the test. It's virtually impossible to achieve OTP from that point, can't blame the Captain for being pissy about it, but certainly wasn't the F/O's fault.
As for not answering the call....
