what is the reason for high attrition rates in call centers?

i agree with that. here where i'm at, working hours in a call center is usually in the graveyard shift to catch with the timezone. and since most people and or our bodies are not used to working at night or sleeping during day time & that's one of the reason why we get stressed out. from this are health risks which leads to attrition. in addition to the stress, not all people are used to be yelled at by aggitated customers. no matter how many explanations we tell our agents not to mind irate callers, they usually can't get the hang of it. we can't blame customers for being irate on something they're paying for which is not working. we also can't blame agents on what they feel being shouted at. we pretty much can't blame emotions.
