They treat you like a robot with the non-stoppable back-to-back calls, not realizing you're a human. Even worse, one of the back-to-back calls is a very long call about a client elaborating a lot in the complaint, it's already passed your lunch break, you're very hungry and the call won't end. By the time it's over, you're already mentally exhausted.
Seriously is a call center one of the worst job positions ever?
