BeeTee - again no idea if this was the contractual situation here, but it is becoming common in FW private flying too that captain has to "tender for bids" to "provide flying services", through his own one-man "company", thereby giving the beneficial owner (usually through another offshore holding company) to terminate services on any pretext. It is a convenient arrangement that absolves the wealthy from paying health insurance, social security, pensions or any of the other expenses involved in employing a professional pilot.
