My point is that no matter where you put the people who were hired for what they are, not their ability, are harming the companies they work for. I'm thinking of one person in particular that my company keeps trying to find a job for that can't be screwed up. No success. And if you suggested that person was an equal opportunity hire, you'd get a pencil through the eye, and you would be the one fired.
Sounds like this particular person needs to be let go. Of course that's easier said than done. There are ways - I've seen the self termination....make the job unpleasant enough so that they leave. Or, just look for the first companywide layoff opportunity. That happened at one of my previous jobs - they laid off (or early retired) several thousand workers. There was much wailing and gnashing of teeth in the local media, but for IT at least, it was an excellent way to trim a ton of overpriced deadwood that needed to find a new job, anyway.
Got a buddy who took a gov't job, and had a person foisted on him that sounds like the guy in your company. The person couldn't pour water out of a boot if the instructions were on the heel.....
Buddy went to his supervisor and said "What can I do? This fool needs to be gotten rid of." Supervisor said (quote) "It would be faster to go down to this idiot's cubicle, shoot him, do the jail time and come back, rather than go through the firing process."
So....my buddy did the same thing that happened to him - foisted him off on the next sucker, er, new manager, to come in the door.
Your tax dollars hard at work.
