2. Peter Gibbons - Office Space

Peter Gibbons (Ron Livingston) is one of the more dangerous employees on this list, because not only is he totally fed up of his job, but he doesn't care (while doing
just enough not to get sacked), and he's intelligent enough to actually pose a risk to IniTech. When Peter's friends are laid off while he gets an undeserved promotion, he devises a plan with them - taken from Superman III - to steal fractions of cents from the company's transactions, such that they'll accrue a vast sum over a few years. Though he might have been nice and competent enough when the gig began, it's hard to say that he's a model employee once he's hynotised into not giving a s***, and
especially when he resorts to ripping the company off. Still, he manages to skate through because his under-appreciated colleague Milton (Stephen Root) burns the whole place anyway, erasing the records of their fraud, so good for him.
