I think it's not about working alone. He obviously likes working alone, what he doesn't like is that lack of team work. As in his previous jobs, he had team interactions. His current job doesn't offer that same peer-level of interactions and that's what sucks. You may be working from home and loving because you may have interactions with peers at your same level but he doesn't have that. And the board, which should be close to that, doesn't offer the interaction and challenges he desires.
