It depends a lot on how you structure your shifts; the problem is getting
everyone 40 hours without unnecessary overlap.
The TV master control facility in which I'm working presently does it
by doing overlapping 10 hour shifts; it takes 10 people to have 2 on-shift
at all times. You work 6 hours with one person, and 4 with the other.
Your 3 teams estimate is, I suspect, derived from dividing 24 hrs/day by
8/hrs shift... but that doesn't take weekends into account, and you don't
necessarily want to have 3 more teams who only work 2 days a week.
I don't think there's *any* way to do it that guarantees you'll always
have the same people working together; fortunately, I also don't think
that's all that necessary in that environment.
