With every job comes some kind of danger. Whether you drive a bus or you're a lawyer for a fancy firm, everyone is exposed to some kind of workplace danger. In fact governments regulate that shit and have case studies and laws in place to prevent the harm and/or death of their employees. Sex work is no different to any other industry, however the immediate risk to a sex worker while doing their job is a lot higher due to the social stigma and lack of regulations and laws in order to help sex workers do their job safely.
