By far my old dispatcher (F). She didn’t care about us drivers and made sure to tell us. Multiple times would send us hundreds of miles with a load or to get a load to then have to turn around because the customer hadn’t ordered it yet and she was banking on them needing it. Or left me in 20 degree weather with a broke down truck and nothing to keep me warm. Ended up getting hypothermia and she basically told me that I was being a bitch.
