Jay that's awesome, reading your posts literally put a big smile on my face! So wait, are the blue trucks not owned by Amazon?
So basically to avoid liability and unionizing, all "prime" deliveries are through contract companies. We wear Amazon uniforms. We drive Amazon branded vehicles that the contract companies lease through Amazon. All specced out by Amazon. All branded vehicles also use 2 different driver tracking / safety systems... All vans use eMentor, which tracks acceleration, g force, etc via the OBD port and an app on a phone. Most also have these really annoying AI cameras that will record clips and send them to your dispatch if it senses you being distracted (phone, etc) or like... Seatbelts off, speeding, red light / stop sign violations, etc. Most of the larger vehicles (step vans and the stupid van / box truck hybrids they developed to circumvent DOT regulations, called CDVs) only have the cameras.
A lot of companies have just as many or even more unbranded vehicles as the blue vans though. Both owned by the companies or rentals. Those still require us to use the stupid app on the phone to track safe driving. My company has 33 vans. 5 are branded stepvans, 2 are the new CDVs, 12 branded 2020 Ford Transits, 8 branded 2019 Transits, 1 Branded Ram (RIP. 2021. Had 6k miles on it and was wrecked by a new driver. My favorite van. It's been in the shop for months), and 2 unbranded smaller Ram vans we use for rural areas. My numbers may be off so take it with a grain of salt lol.
But yea. We aren't Amazon employees but Amazon has control over all aspects of the job. They can call my company and permaban anyone from delivering at any time, essentially firing them. They control the minimum wage at each station. They have super high metrics they want companies to meet to get priority in route numbers... It's a complete shit show. I like my company, owner, management (I even may totally have a work crush on one of my managers... Shhhhhh. It's nothing though lol). Most of my coworkers are cool... But Amazon itself sucks.
