Company X anticipates getting a contract so they staff up for it. Joe gets the job. The company doesn't get the contract they lay Joe off. Where in that scenario is Joe skilled or unskilled at doing his job? The only thing I could say is Joe was skilled at getting through the job interview filter at company X and nothing else. Say Joe works for company X, and company X goes under. Is Joe less skilled than Sue who works for Company Y? There is to much noise surrounding why companies hire, fire and the process by which they do so to claim any sort of tautology around skilled = employed. Maybe if you limited it to up or out companies.
