Pros
You have a lot of autonomy in this job and you work outside which can be great depending on the weather where you live. In my city, you get more than enough overtime, so that's great if you want or need it. You earn time and a half after eight hours and double time after ten, minus 30 minutes for lunch coming out of your overtime. Some people complain about the management, and while some of their expectations are unrealistic, mine has treated me fairly and well. You also get to drive postal trucks which are fun and you can pretty much park them anywhere which makes you feel like a boss. You will lose weight while getting to interact briefly with the public, and those are mostly positive encounters. I like the job but I've only been carrying for a little over a month.
Cons
There is a period of time, dependent on your area, where you are temporary and you do not earn any retirement benefits and neither do you receive health and dental. You are at the beck and call of management and I've heard some bad stories of how that has turned out for some people but I don't have firsthand experience. You only find out your schedule one day in advance and you must work every weekend. It seems that they are completely understaffed, and whether that's due to the USPS's convoluted and ridiculous hiring process, them trying to save a dollar anywhere they can, or because they can't retain new employees I don't know. At my station, there is supposedly a forty percent retention rate among new CCAs. You will be asked to move at paces that are impossible or would be unsafe. My recommendation is to not complain to management but take care of yourself and do the best you can. Training is pretty short and you can expect to learn how to do things by trial and error, catching flak when you don't know what to do because you weren't trained. Again, don't take it personally, find a regular who knows what they are talking about and ask them. The hours can be extremely long. The training "Carrier Academy" is pretty useless and they treat you like children, but if you can survive two weeks of it without falling asleep, you will be fine because you'll learn on the job. It's worth sticking around, so I'm told, because the regulars don't get treated the same way and they are compensated for their work fairly and more inline with a living wage. for doing the same job. I like the job but just wanted to give some of what I've observed. Most of my criticism of the management is directed at higher ups who I've never met and don't want to meet. They seem incompetent and I wonder if they wonder why they have such high turnover or just don't care. You are docked a half hour of pay every day for lunch so make sure you take your breaks no matter how busy you are. This goes along with taking care of yourself even if you are being pushed to meet deadlines.
