I see. Fortunately, friendship at the jobs I've had never proved to be an issue. I guess because my work is highly collaborative, this is often a natural outcome.

I'm thankful for having the luxury to choose my workplaces and I would never pick a place that expects me to leave my life at the door. Of course though, I respect my colleagues who wish to do so but I have found that very few of them wish for a strictly professional relationship.
