I'm pretty much the opposite. If people like that are shitty at their job, hopefully that gets noticed and she gets shitcanned before she blows some major contract and puts the company at risk or costs the company big bucks. And the "Let's give her a chance" bullshit is just that: bullshit. She's had her chance. She's already proven herself incompetent as well as a liar and generally unpleasant person to work with. Why is she still working there?
That's rhetorical, by the way. Wet Helmet, I feel your pain. The more time you spend in the work force, the greater the odds that you've worked with assholes like this, and I've definitely met my share. If they fuck up, whatever. But if they fuck up and it affects me, my job, my company, we have a problem.
