On a recent trip down to oz, it was a normal sector to the far east... got to the bar in the hotel and got chatting to the pilots and other crew.
Arrived in SYD and the FO was a little quiet. As we'd been chatting previously I sat next to him on the bus and asked him if he was OK. Turns out he'd been having problems with the missus and it was weighing heavily on his mind. He didn't feel able to talk to his colleagues in the cockpit as he was afraid they'd think he was 'weak'.
When we got back on the plane to start our trek home I asked the guy how he was and he was again a bit quiet and seemed sad.
On arrival on the far east I offered him a quiet drink and a chat in my room before we all went out for dinner. Suffice it to say that we didn't make it out to dinner as he spent 2 hours in floods of tears in my arms in my room.
We went for a walk the next day and he admitted to me that he didn't feel able to tell the company about the problems he'd been having in case they suspended his flying licence.
Such a shame to hear a really nice guy was having such a hard time with so little contemporary support...
