EQUAL opportunities legislation has brought a heightened consciousness of political correctness to the workplace. Descriptions of the personal and professional qualities required by prospective employers in the job appointment pages in this and other newspapers are sometimes exaggeratedly contrived so as not to offend any sensibilities. However new boundaries in political correctness were set this week by a newspaper in Hong Kong which ran an advertisement placed by a computer hardware company seeking production staff, stating: "sex, experience and nationality not essential." Any androgynous, inexperienced, stateless ethnic minorities in search of work could do worse than head for Hong Kong.
