[Work] It's been a while since I've needed to add a pilot onto my No-Fly List. I think I've discovered one today, though.
He could not make less of an effort to socialize or to attempt teamwork if he tried.
He isn't being actively antagonistic or anything, he just doesn't seem to care.
...so I'm now ignoring him unless I'm required to interact with him for the job, and putting out just as much energy with it as he puts in.
