Most careers begin and end in the call center, whether it be sales, claims, or some facet of customer service. That means all day, everyday, on the phones. Having a two day weekend is non-existent for most departments and rarely does one get to choose their shift. Most supervisors and management are more interested in wringing the most productivity out of your current job than in helping you rise to a better position, so if you aren't a self-starter always looking for a way off the phones that's where you'll stay. Turnover is high in the entry level positions and a large percent leave in the first two years.
