Call center workers are generally unskilled workers who are being paid far beyond what the work merits.
Had a friend who quit working at a call center. The best job offer she's had in 2 years is at 10 dollars less per hour than what she was being paid at her terrible job. It's a job usually reserved for women, while unskilled men have to go break their backs for 14 bucks an hour. Boo-hoo. Yeah, I know it's a shitty thankless job... that's why they're so overpaid. The majority of unskilled workers have jobs equally as shitty and often for far less money.
If you want a better job, acquire skills. Answering the phone isn't a skill. If monkeys could talk, they would do it.
