I'd welcome side projects as a mental diversion, but only for a brief while. I don't expect my team to be always on, and I expect them to be distracted partially. I just want them to get the right solution within a reasonable amount of time. It's easy to tell when someone gets sucked in to something they aren't supposed to be doing, versus just taking a much needed mental break without going so far as to take a vacation.
