Sure it's a weakness, but they (management) don't care. If the developer leaves, they'll hire another and in the mean time the remaining devs get to pick up the slack. It's actually a convenient excuse for the schedule slipping; they blame it on the developer who left because he "wasn't a team player", even though management knows the real reason is because they simply don't ... know ... how ... to ... manage.
