Sorry to digress a bit, but all this reminds me of a wonderful book called "The Temp", by Serena Mackesy. It had echoes of this: she felt that as a "temp", although working very hard for peanuts and no employee rights, she was held in very low esteem by everyone else in every office she worked in. It had some fantastic lines, some of them pure Mumsnet fodder:
"I go to a different place where I'm known behind my back as 'the temp' and to my face as 'um, hi.' I've been counting, and do you know how many people have called me by my name since I started temping? None, not one."
"Lucy (I'll believe in the classless society when City executives are called Kylie) purses her lip before saying: 'you're late'."
"One boss of mine awkwardly shook my hand, then wiped his hands on a sterile wipe, before dropping it, two-fingered, into the bin. I'm so used to odd reactions from new bosses that I thought this was a new imaginative way of making me feel unwelcome; but it seems he's terrified of germs. He must get through more of these wipes than the average surgical unit; he uses them for everything, paying special attention to the crevices around the drawer handles."
There's a wonderfully gratifying scene in which "the temp" uses her anonymity to help her friends get revenge on a violent rapist. "He's done it before. The social services know who he is, the police know who he is, and twice a jury has found him so plausible with his classical good looks, his well-cut suits, that they've let him off without a blemish to his name."
OK. I'm "super". I've just saved them from building their oil rig upside down, and I'm "super" like a member of a hockey team. But I'm going to make the woman from HR who's firing me actually work a bit for her salary and space in the car park for her air-conditioned Vectra.
There was also a chapter comparing office stereotypes to characters in children's books. One of the best ones was: The White Witch. A woman of a certain age, who fought her way up when the system was much tougher on women, and has developed an icy personality. Great clothes, no sense of humour.
