It is important because safe working conditions should be a fundemental human right no matter what industry one works in.
The laws on prostitution are outdated and need reform. While it is legal for a person to accept money in exchange for sexual services, it is only legal if there is noone else in the premises.
If two or more people work together then the law classes the premises as a brothel and that is illegal.
Not all prostitutes are forced into the profession against their will, many enter into it freely and willingly despite the impression given in some parts of the media. These workers have the right to work safely and without fear of attack
I know that any proposals to liberalise the laws on prostitution will be met with moral outrage in some sections of the press but in my view, people's safety must come first
