I heard a management culture story about the company recently. Not from a dispatcher. Upper management identifies certain employees who want to be managers. People who are willing to lean on and walk over anyone and do anything to further their own careers. These potential managers are hired into mid-level management, acting as "lieutenants" to the upper managers. The lieutenants do the dirty work and will cheat and lie to bust (some) laborers either by behest or by independence to impress the superior.
Not that all mid-level managers operate in this way. The problem for these lieutenants is that they never get promoted further. Because they have already demonstrated that they can't be trusted! They're caught in a trap.
