I'm a journalist -- technically you can't plagiarize yourself, so while not best form, it's not really anything "wrong." And often there's certain phrases that as a writer you are going to use over and again (he took it well beyond that though). So that's why he was still around. But yes making up quotes is WAY across the line. I'm curious if he just up and resigned knowing he would be fired; if I were his boss, I'd rather fire him to make sure people know how serious his transgressions are.
Self-plagiarism is most definitely not as "wrong" as plagiarizing from someone else. But in some contexts, the amount of work you've produced for esteemed publications is essentially part of your prestige and resume. To have significant number of pieces actually just be recycled material, while bragging about how you were published in X, Y, Z magazine, is looked down upon.
Agreed Danso. Although think it could be argued technically that it's not "plagarism," but could be considered to be ripping off the people who paid you for the article. And there is copyright issues depending on who owns it. And, of course, it's sleezy at the amount he did it. So maybe several levels here.
