I don't blame the unions, or the people that are in them, one bit.
I just don't for a second buy that this isn't really job protectionism (Which I'd expect them to do) under a popular veil of other people's safety.
Some of the salaries involved are ludicrous for the job (not especially guards), and it's poorer people who end up funding it however unpalatable that sounds. This level of self preservation by the unions is exactly what they seem to hate the Tories for.
If Unions are genuinely concerned about the effects of cuts on passenger safety there is little or nothing they can do about that directly.
What they can do directly is campaign for their members to keep their jobs, and thereby indirectly maintain passenger safety.
They're fannyin abaht - but they are trying to score.
Similarly, if as a teacher you think young people are being tested to destruction, and you see it affecting their mental health - that's a political issue, to be voted on. You can't act collectively on it even through the union, but what you can do is, say, advocate for reduced workload and refuse to mark those tests.
There's a big teachers strike in the US at the moment being run along these lines.
If a Guard's concern is to protect the public then it is precisely only by acting in (apparent) self-interest that they can protect the public.
I'm not trying to romanticise what's happening, just point out possible practical considerations.
Point taken about poor people paying for it but, for me, that's structural. Symptomatic of the social order we've bought into.
The way I see it, framing it as Unions vs The ZHC Freefolk is buying into divide and rule.
