AC in truck cab is not good, then in the box it s sub freezing. You alternate very hot/very cold all the time. Milk crates are in random order in the box, imagine a giant Tetris where you need to fill and move thousands of pounds with a metal hook to prepare yourself your delivery orders while the reefer unit blows sub freezing air in your face at 3 am. Delivery orders look like a soviet union alternate reality, printed by a daisy printer of the 1980 era. Dash cam spies on you. Lots of favoritism, some people transport empty crates while some super heroes do a great job day after day. This food industry field has strong competitors, which is why they are shutting down plants.
