Verso is right, it was definitely telefundraising... we were the fundraising branch of a regional "non-profit" agency. The "non-profit" was in name only and was accomplished through shady accounting practices beyond measure... Put it this way, shortly before I quit, I was being considered for management of another office about two hours away, and I was let in on the fact that $0.06 of every dollar that we raised actually went towards the cause advertized. When asked "how much of this actually goes to cause XX" we were trained to tell customers (and, again, through shady accounting and legal loopholes, the lawyers had found away to make this statement "technically true") "fifty cents on the dollar" but that fifty cents was on the dollars left after rent, utilities, salaries, advertizing, mailing costs, and whatever the hell else was paid for.
Very, very rarely were we harassed or insulted (the "cause" we were raising money for is pretty universally acknowledged as necessary and good, and we had tie ins with orphan organizations to boot). The biggest drawback was the repetition and monotony. And the pressure to "collect" was pretty high too (saw SO MANY people come and go in six months. highest turn over job I've ever had).
But all in all, it was a fun job while it lasted. The three of us who were addicts became fast friends--and they were both good guys for the most part, we had a lot in common besides drug dependence-- so the office environment was enjoyable, I was high every day, most nights we'd go out to a bar after work and get shit faced, sleep til 2pm the next afternoon, wash rinse repeat.
