HONG KONG may be losing millions of dollars because sexual harassment makes it difficult for women to concentrate at work, a women's organisation claimed yesterday. Spokeswoman for the Coalition Against Sexual Abuse, Linda Wong Sau-yung, cited research carried out in the United States which showed workers' productivity was reduced in a hostile environment. ''You cannot provide good quality work if you are under sexual threats from your boss or colleagues. The company will also lose experienced or skilled staff who prefer to leave their jobs to escape further harassment,'' said Ms Wong. The coalition is organising a territory-wide survey on sexual harassment. Ms Wong said: ''The interviewees will be asked about the company's policy against sexual harassment and if they have established special complaint units. We also want to know about past cases of this kind.'' Women's organisations urged the Government to pioneer the setting up of prosecuting procedures. The coalition hoped the campaign would raise the general awareness of the problem. They would also give advice to companies which planned to establish a special policy on the matter. The Coalition Against Sexual Abuse said the lack of channels and well-established legal procedures to deal with sexual harassment complaints worsened the problem. ''So far as we know, neither private companies nor the Government itself has worked out a clear policy to manage the complaints of this kind,'' said spokeswoman Ms Wong. ''Some victims have to spend months finding us to voice their experiences. ''One of our clients contacted us until she has developed skin diseases because of the stress of frequent sexual harassment. ''But we cannot do much for them either.''
