Are you a Current or Former Employee? Former job since 2010
The culture can best be described as "cover your a**".
Support from Management
There is no support for anyone wanting to move up, direct supervisors are concerned that you will want to replace them.
You work as an individual on projects.
Level of Autonomy
Your every move is watched and critiqued. This is especially true of all drivers logs.
Communication between customer and driver is great, not so much between direct supervisors.
