To be honest I've endured more violence growing up in my neighbourhood and working in the retail business. But I'm just telling you my personal experience which may differ from other women.
Do sex workers suffer from violence? Sure they do. But women in general suffer from violence in our society in all sorts of forms, and sex workers are women - a lot of us working alone so of course we become more vulnerable to attacks. I work as an independant in a very safe (and er..."upscale" I hate that word) enviroment and i'm very good with my safety procedures but if I worked in the streets most probably I would have been subjected to quite some violence at this point. I've worked in the states for some time and I saw that women over there don't report attacks while here in the UK they do it (I guess because it's legal).
I think this is very helpful in illustrating what I was getting at, and why we are often so irritated by programmes made and articles published about our work - sex work does not exist in a vacuum and the often total lack of
any context is one of the primary reasons why these depictions of us and our job are generally so useless. Will there be companion programmes covering other jobs, and how people who do them go about their day-to-day activities?
If you don't want to lead the people you engage with, might I suggest you don't blaze in with questions like 'tell me about any violence you have experienced' and so forth, because people will tell you about what you ask them about, and if that's all you ask them about it would be easy to assume that it is something which happens a lot. Why not ask them what a typical day or week is like, and let them tell you? This way you can get a realistic picture without manipulating anyone. Unless you actively want to, that is.
People who do not take security precautions, take silly risks and generally behave irresponsibly are more likely to find themselves in dangerous situations, but those who are more careful, have good security procedures in place and operate responsibly are far less so. What they do for a living (or a hobby, or for their holidays) is nothing whatsoever to do with that, and you seem to have already assumed that sex work is itself inherently risky. What
is inherently risky is taking unnecessary risks.
People who put on a blindfold and then walk across the M25 are more likely to get run over than those who skip the blindfold and only ever step into the road at a pelican crossing. It isn't rocket science.
