Unions are not evil, they are simply people following their own incentives. Indeed the same can be said for the vast majority of humans and inflammatory language like that does nothing to further understanding of their points of view.

As for "punishment", are you serious? What punishment? By whom? Under which terms?

Personally I'd advocate for my work disciplinary interactions to be private between me and my employer, as I suspect would most people. The police have a public interest counter argument to that otherwise rational expectation. So what's the middle ground? Can there be generalised stats released whilst maintaining privacy? Perhaps privacy simply cannot be maintained in this instance (for example my professional body would publish the results of disciplinary hearings to the public record I believe).

Accepting that you don't like the result I find it hard to believe you can't see that there's a conversation to be had and that both negotiating parties had a case to make.
