Oh a low life parasite, if I had a quid for every time I was called that! At the end of the day, most large companies are morally questionable and having the experience of working at a PPI company most people there are either students, parents, young people from school and just generally anyone trying to get by. I was screamed and shouted at a lot, and I don't blame the people for it, however I do think that anger is best directed at the top to change legislation and bring these companies down, or at least make them more regulated.
The people at these call centres are real humans, and are just trying to make ends meet. These jobs are, for many like myself, stop gaps for people who are between jobs and can't afford time off. I wouldn't judge anyone for working there, as I'd do anything to put food on the table for my kids.
