Pros

Cons
The reality is the USPS is in financial chaos. Every single thing they do is intended to cut costs. As a CCA, you are filling in for a more expensive, career carrier. You're the cheap help who will be worked to the maximum. Depending on the station, you can expect no set schedule, only the rare day off (perhaps once a week, if you're lucky, and at random times and without notice), injury-prone conditions (especially in winter), and disrespect from some supervisors. The USPS does not want career employees; they're too expensive. And they'd rather have all non-career workforce. So they bottleneck the process of converting to career ("regular"). Be prepared to be exploited for up to two years, then you're going in a bad neighborhood for a while. You will also likely be sent to bad neighborhoods as a CCA. You may even be stationed in a bad area so you're there every day. Listen, if you get injured as a CCA, you are screwed. Theoretically the USPS will pay you for up to six weeks but then you're on your own. In reality they may even fight your compensation for the six weeks. Oh, and you're working Sundays on amazon packages. How depressing.
