This suggests that Ryan has confused "leadership" with "management". Good leadership means that people are all working to the same goals, good management means that people are working efficiently.
If you want to fix rumors, cliques, and back stabbing. Look to your leadership. If you want to get more done with the same number of people look to your managers.
It's a people problem! Hire better people that won't engage in petty crap like that...
You "fix" that by putting everyone on the same page going in the same direction. That is leadership.
If you've got someone who comes in at 10AM and leaves at 4PM and takes a 2hr lunch break. But they start no rumors, nor backstab, nor empire build, that is a management problem.
