A few thoughts. I worked at UPS for over 7 years, based on the union and their seniority no one is becoming a full-time driver anytime soon off the streets, at least at my hub. Thats something you have to put in many, many years for. I would also say just based on their trucks vs express its a rougher job. No a/c for one. Most drive sprinters at Express, there is no comparison. A brown truck will beat you up just as much as the job itself.
As far as the post office, those guys work 7 days a week lol, and have to deal with all of amazons bs. Some people like overtime but you are guaranteed to have no life working for the post office.
Im newer myself at Express, but honestly if they can now stay true to their 10 step plan, I dont think there are many better driver jobs out there.
Anyone disagree?
Edit: seasonal drivers at UPS? Yes it is absolutely seasonal, they tell you that up front.
