Shifts were set with no overtime, no paid holidays, no shift swapping. It's an inbound call center whose customers hold credit cards backed by a number of vendors (WalMart, Sam's Club, JC Penny's, etc.). Most of the job includes taking payments, making payment arrangements, requesting deferments, and explaining charges. The majority of customers are upset when they call; I would not recommend this job for someone not experienced in customer service or for someone who might take customers personally. To be fair most customers just want help or an explanation, so long as you can remain calm and helpful it isn't too difficult.
Non-physical work, talking on the phone with customers.
A decent amount of upset customers call in - the job requires patience and obectivity.
