The terms and conditions of employment is a matter between employer and employee only, it is nobody else's business.
Err, until the employee stands in the street waving a banner about stating (often incorrectly) those T's & C's. or indeed screams at me from a passing bus, or takes out a full page advert in the paper, or produces a video with a poor CC member explaining her woes, or causes my annual holiday to be cancelled, or.....
I think privacy in this issue went a log time back....
