I worked in the customer service call center. As far as call centers go, there really isn't anything better than FedEx.Guaranteed 40 hours per week, with the option to leave without pay if it is slow. Full benefits, great insurance and retirement options. Most of the calls are people looking to track shipments or schedule package pickups, and I'd say you would look at maybe one or two irritable customers per day. Peak season is a nightmare, with mandatory overtime, longer shifts, and non stop calls, but FedEx tries to give little parties and other things to keep morale high. Overall, it's a great job that pays well, and you can move anywhere within the company.
Benefits, paid time off
Very strict with scheduling, you will be yelled at by customers
