Hi Poppi,

Have seen a lot of suggestions here, about taking actions to have him charged and so on. Have you thought about what may have made him make such advances towards you, did you for instance misled him about your social life etc... This fellow may not realise that he's causing you such concern, he maybe thinks that you have some feeling even though, you may have sent reply via sms to tell him to back off, some men, and this is maybe a cultural issue as well, some men don't see themselves being put off the scent of a lady, by her simply resisting his advances. Do you see where I am coming from? Anyway before the sun sets on another day, you need to sit this fellow down in the office of a colleague (maybe yours and his supervisor), and tell him bluntly that there is no feeling for him, apart from the time at work, you'll not entertain thoughts of spending time with him, and that if his advances continue, you'll do the following, ie lodge a "formal" process with your employers about being sexually harassed, in writing outlining dates and incidences, to which the company MUST respond under it's obligations to employees within a set period. Failing any action from the outcome of your formal complaint with your company, then you'll be reporting the same incidences of sexual harrassment to the Labour authorities in Qatar, and the Police as well, you should let these comments be heard both to the perpetrator ie your co-ordinator, and your boss, and duly recorded in the companies records. He may receive a warning, but that will depend on the company, don't have any hesitation about his future, many people tend to think they are safe within a company, but this kind of thing is "criminal" and shouldn't be tolerated by any company wanting to keep him on, he should have to show cause why he shouldn't be dismissed if he eventually gets charged formally. Remember this initial meeting is to be a "closed door" meeting, and ask that the boss record the events spoken about, if the man (harasser) is smart, he'll stop and think what he's doing is wrong, if he's not, then he should expect the full extent of the punishment from all levels, ie company to the states laws.
Most important of all, don't show any sign of acceptance, be courteous at work but don't encourage future comments from your coordinator unless they are for purpose of the project/business, ALSO very important don't entertain thoughts of leaving the company, unless you have viable alternatives ie jobs worthy to transfer to.
