Knight Transportation was a good company when it was owned by the Knight brothers, however, once they left and the management was turned over, there was little to no governance of any kind. People were left to do what they wanted. There was either too much supervision or none at all. Some departments were left with managers who behaved like children and did not think twice about harassment and abuse, while others treated employee's properly.
There was no in between. You were either used and worked without any supervision or guidance and left with those who did not work at all, or you have supervision of the worst kind where the managers wanted production and offered no help whatsoever.
The company was better off when the Knight brothers were still involved.
