For all those who see nothing wrong with CVR monitoring; you imagine carrying a live mic/recorder with you on your whole work day. It wont be just the company monitoring it, but government/authorities too. Once the CVR recording is off the aircraft, it is open to all who think they have the right to listen in. Think of all the divorce lawyers who would be interested in cockpit conversations!!
This is why there was a lot of resistance to CVR when it was implemented, and why it was guaranteed (Chicago Convention) that recordings must be erasable if no incident had occurred. It is also why CB's have been reluctantly pulled in the past when this confidentiality has been breached, by police warrant or other legal requisition.
Pilots are the first to agree that it is a huge flight safety tool, and support its use for flight safety. FLIGHT SAFETY ONLY. Not snippy managers looking for gossip in confidential conversations.
