I have long believed that true communication is only possible between equals in a venue that everyone considers safe.

If you have the ability to significantly change someone else's life, they will produce submissive and defensive behavior just as though you had them actually pinned to the ground while baring your teeth. In the end, a manager is just a skilled laborer with a different set of skills.

There is no particular reason why the ability to organize a labor force should automatically result in authority over it. The manager does not always need to be the boss. I imagine that some business decisions would turn out differently if they had to be backed up with evidence and argument rather than authority and the threat of job loss.
