Now let's also imagine that you already have the trust of your direct reports (I would think a lot of Amazon managers don't but that's neither here nor there). You explain a policy to them - they have to be in the office 5 days a week or Things happen, whatever they may be. This person just refuses to do it. Is the manager to just say "oh well I don't want to 'be a dictator' so I'll just let them ignore this policy?" Of course not. They'd be abdicating part of their job if they did that.
