-Typical call center environment: heavy emphasis on your stats/phone time, which is averaged out by month. Certain activities, like direct extension calls/voicemails/emails, don't count towards your totals. If you're a nice person who customers tend to get "attached" to, you will find yourself doing a lot of extra work you don't get credit for.
-It's difficult to get fired. Even when someone is so verbally abusive that half the office refuses to work with this person.
-If it's 5 o'clock and you're on the phone, you have to finish the call. Even if you're there two hours late or more. You get paid overtime, which is nice, but it's hard to plan appointments, etc when you never know if you'll get out on time.
-If you're one minute late, you're in trouble. Not very understanding of illness, traffic, etc.
-You will frequently find yourself doing other people's work and taking the heat for their mistakes. This is partially because of the emphasis on taking incoming calls. People delay answering emails, voicemails, etc because they haven't gotten their calls in for the day which leads to annoyed customers, higher number of incoming calls, and less efficient handling.
