Seriously, if IT isn't serving the needs of your business, your IT is staffed with idiots and whiny bitches like the above poster.
In the real world, people like you get sacked.
Sorry, but no. In the real world, IT pushes out Windows installs laden with all kinds of crapware (such as McAfee), resulting in systems that run dog-slow and crash and freeze all the time. These IT departments are rewarded for this incompetence with continued employment, bonuses, etc.
Also in the real world, HR departments are staffed with idiots who cause all kinds of problems with the company, yet again these people are rewarded with continued employment and bonuses.
In the real world, incompetent people are NOT sacked, they're given more power.
I don't know what "real world" you live in, but it's definitely not the one I live in. Maybe you live in the parallel universe that Star Trek: TNG is set in, where everyone is hyper-competent.
