I heard something interesting a couple weeks ago. Did you know that when you place your fast food order at the drive-thru, the person you're talking to may not be in the building you're driving around? True story. I read somewhere (I wish I remember where, now) that some of these are routed as actual 'calls' where people process the orders (and ask you to super-size or add a sundae, of course). Who'd a thunk, eh?
I've worked in various types of call centers more than once. With the right company and decent co-workers, it can be a relatively pleasant job. Usually if it's the sort of job you're good at, you could do it for just about any company. I'm glad to see there are still companies willing to utilize folks in call centers in U.S. places like South Dakota. It's one of those jobs that is admittedly easier to outsource, but outsource doesn't have to mean out of the country. ;)
