On further review, the OP in the DUmmie thread is likely one who isn't capable of HOLDING a job for more than one pay period due to his overwhelmingly asinine attitude wherein he constantly reminds others around (and particularly ABOVE) him of how lucky they are to have him around.
There was a guy like this in my shop recently. Dude was convinced he should have come in as a supervisor, not an electrician, despite his resume (Navy nuke) not being anything spectacular and those around/above him were far more qualifed and experienced.
He quit less than six months later, convinced we were all out to get him, that he was better than us, and that he'd be in management at his new job (another nuke plant) in no time.
Last I heard, he was on the verge of quitting there as well, less than six months in.
