News Corp's Loyalty to Staff?

The Murdoch Empire is enmeshed in crisis about its phone-hacking activities. Now, four "Sun" staffers and one serving police officer have been arrested in relation to charges that the police have been paid to hand on stories to "The Sun". The interesting thing is that News Corp is admitting that it has dobbed in its own staff, via a Management and Standards Unit set up as the phone-hacking scandal evolved. It must be confusing times for News Corp staff as the rules change in mid-game. One day, it's all on; the next,it's all evil. They must find the adjustment to such a wide moral compass challenging.
