I'll add this much to the dislikes column:
I never feel like an employee, associate, team member, etc. at my company, merely a contractor.
The company you work for is only as good as the last paycheck that clears the bank. Freight companies included. They'll ditch you in a heartbeat if it saves a nickel.
There are plenty of trips that I say to myself in the middle of the night, "What am I getting out of this?"
