I have quite a big issue with this.
Many pilots would probably have an issue, if their management has the possibility to listen to all their conversation of the previous mounths...
It is like video recording of the cockpit, nobody denies that this is technically possible and can be incredibly useful. But nobody dares to mandate it for obvious reasons.
If data exists, it will be (mis)used.
Probably this will be just another case, where all the interesting details are
not recorded. And that may well save some from very expensive lawsuits...
