Why are the clerks treated like royalty and the carriers treated like garbage?

The carriers are pressured to work with time constraints, forced to work fast, and we’re pushed to the max with our workloads, yet the clerks are under no pressure at all. Ours, you can find reading books, in the break room, or on their phones playing games, all while on the clock. There’s no respect for us, what we do, and how hard we work… very sad 🙄
