some folks I might let them hang out to dry in their own crap.. ultimately it's a team though so work toward the goal. personally I have issues with authority and being told what to do but am the opposite way with clients/customers and am damn near OCD about the quality of what I produce.. I have no desire to let the end product fail because of a weak link unless that weak link really needs to get got... we all mess up occasionally so having a team that is cohesive and helps lift/support each other is pretty nice to have and you don't have that when you stick solely to your own scope.
