"Breach" is not the right word, because this suggests an unintentional act. This was intentional, which suggests a far stronger word whose precise definition so far escapes me.
I'd suggest a simple word pair instead: "trust betrayal"... as in 'biggest privacy trust betrayal in our time'. Particularly since employees have a trust that their employer will behave with integrity to guard the personal information they've entrusted to him - and this is anything but fulfilling such trust.--
