Well, it isn’t me who is adding layers of interpretation then, as at no point have I said that people in the jobs you mentioned don't have unions available to them.
What I did say is that ‘is saying “oh, they can join a union” something that passes for a left wing view’?
It is morally reprehensible to squawk that people can ‘get other jobs if they don’t like the ones they have.’ At no point should that be an acceptable thing to say. That attitude is how appalling practices happen and continue to happen.
Changing jobs is not straightforward. Take the care sector for example (I used to work in it.) They are desperate for care workers so theoretically you can change jobs at any time. But. But but but.
you need a new DBS (£40)
and new uniform (£20)
and three days mandatory training (unpaid, so you lose three days work)
It is easy to see why people end up staying.
And yes, you can join a union but with zero hours and / or crap shifts being the threat over your head, you won’t make too much fuss.
That is why I hate the Christmas Day thing. It’s something that runs deeper than Christmas but it’s something that goes against what Christmas is, or should be anyway, irrespective of your beliefs. The lowest paid spend the day serving the more privileged and powerful. And yes, I know doctors work CD and they are well paid and I know pilots too and even king bloody Charles. But it’s not mostly is it? It’s the care sector and the catering sector and the shop workers and they are low paid women so who gives a shit if they’d rather be with their own families, I just have my milk / go out for a meal / go abroad. They don’t like it? Of course they do; I asked them. And even if they don’t, well, they can get another job, it hardly comes as a surprise, does it?
It’s a fucking horrible attitude.
