It is common for Unions to try and use "Professional Standards" to suppress whistle-blowers.

The Avison Report in BC described how the BCTF slate controlling the College of Teachers tried to censure the teacher who turned a laptop borrowed from a BCTF Slate member of the College over to the BCTF (instead of immediately handing it to the police as required by law). .

From Page 23 of the report: "A BCTF representative attending the same meeting later told her to return the computer to Austin and tell him to get it 'cleaned up,' the report says."
