Hard to sack the guy...
... as he's the majority shareholder :)
What makes it hard for me, is he views IT infrastructure, the same way he views his home network. On impulse he goes out and buys all the latest gear from the apple store (I'm not kidding, he'll go out and buy 10K's worth of Mac gear, because the salesman told him so). I then go round to his (titanic sized) house and he shows me all the gear, he set up himself in about 10 minutes, that lets him, his kids, wife, wifes kids, friends of kids, pets access his home network, not to mention his HomeBrick™. And apprently the fact that everyone and their dog can turn the kitchen lights on and off is a good thing.
The only thing keeping me in a job is I sent all the board directors some Mercedes logo'd USB sticks in the post, with a fake Mercedes covering letter thanking them for their custom, and pointing to a (fake) website offering some great service deals. I then turned up a week later at the board meeting with numerous passwords in hand, pointing out I could have been a competitor, oh and look at the emails I managed to print out!
It's frustrating. My employer is a PR company. I regularly point out, that as a PR company, it's our job to promote, exaggerate and lie about the products we're promoting, in order to make sales. The board agrees with me about this point. However when I point out that the marketing departments for any product we buy, have exactly the same mandate, therefore we should take anything a salesman says with a pinch of salt, I instantly become a heretic, simply because (i'm told) our competitors believe the same salesmen, therefore they are right, and I'm wrong.
As someone else pointed out above, my only option to point out the facts, and collect my P45. But I have a mortgage, children, a nice big sports car and holiday home and we're in the middle of a recession, so, I think I'll stay put, and keep sending the bosses "free gifts" in the post.
