If you're doing your job and on time to work, you will be generally left alone. Hard to get fired for performance unless you do something egregious.
Cons
Very high turnover, not much opportunity for advancement, pay is low, bonuses are small, the US-based call center industry is not booming at the moment - if you're looking for a growing industry with exciting new things happening, look elsewhere. Don't think about advancing to top management unless you marry into the family.
