Liberal feminists/sex work is work proponents....

Well, that was quite a leap. I wonder what other things that OP is to be assumed to be in support of.

I don’t think the DWP should be able to sanction you for refusing any job which you have a strong aversion to. What if I don’t want to work in an abbatoir, killing pigs all day? I definitely shouldn’t have to. It’s the same for sex work. People should have the right to refuse any job they feel unable to do, and it shouldn’t come with sanctions.

The fact that you seem to think it’s acceptable to sanction people for refusing other jobs they don’t want to do is pretty revolting. Being out of work doesn’t mean you should suddenly be deprived of the right to make choices about what is right for you. The government should be working with people who are long-term unemployed to help them find suitable jobs - not forcing them into unwelcome positions with the threat of financial hardship.

And what about denial of service? What if a person is denied service and files an unfair discrimination lawsuit?

If you're (entirely reasonably) balking at that then you don't really think prostitution is a job like any other.

You'll never get a coherent answer to that one!

Another related question: what about consumer rights? Do punters get refunds for "faulty service"? if not, why not?

Another question is how to they make sex workers COSHH compliant under the auspices of the Control of Substances Hazardous to Health Regulations 2002? What PPE would making working with bodily fluids safe, and how should "sex workers" be held responsible for using and maintaining this PPE? How do they ensure that "sex workers" remain safe when refusing to remove PPE for their "clients"?

Good question.

Another question is around health and safety at work >

If it's a job like any other then relevant legislation should apply but this would render the job pretty much undoable.

So how does that work.
