I work remotely, as do all of the staff in my company.
I work closely with a man, let's call him Greg, and we get on together very well and refer to each other as work "besties", yep, we are infantile.
I've have 3 primary aged sons who all come over and say hi to him on Teams meetings etc (only if it is the two of us obviously).
I'd really like to send Greg a Christmas card as I do personalised photo ones, but don't know his address (I do know roughly where his town is but don't think that is going to cut it with Royal Mail).
Is it inappropriate to ask for his address if I put it in context for him? I don't want him to feel under pressure.
He had no partner who might be made uncomfortable by this. We've met in person several times at events and get on well.
YABU: Don't do this, it's inappropriate
YANBU: Sure. Why not?
