MOST young people were ignorant about work and work ethics and about how to choose a suitable and satisfactory job, according to a recent survey on young people's attitude towards careers. Educationalists suggest that more career guidance and anti-corruption education be given in schools to cultivate among students positive values and attitudes before they enter the working world. In a study of student attitude towards work conducted by the Independent Commission Against Corruption (ICAC) in 1989, nearly 30 per cent of the over 2,000 respondents, including 1,645 Form 5 and 398 Form 7 students, expressed the desire to become professionals in the future. ''Businessmen'' (10.3 per cent) and ''executives'' (10.2 per cent) were the next priorities. However, many respondents were doubtful if their dreams would come true. Over 70 per cent of Form 5 students and 56 per cent of Form 7 students were not sure if they could live up to their expectations. Mrs Grace Cheung, ICAC Chief Education Officer, said the findings indicated that students lacked confidence to work. ''They do not know how to choose a career and sometimes they set targets that are too high. Most of them want to be a professional but it is not so easy to be one. ''They should consider more carefully their abilities and qualifications before deciding on their future career,'' she said. Although most schools have career guidance teachers, Mrs Cheung wondered if students were able to get sufficient information and guidance in school. ''Most material is factual and focuses on the types and qualifications of jobs and lacks information on work ethics and value judgement,'' she said. Mrs Cheung's opinions were echoed in another study conducted by ICAC in 1991 on work attitude among young workers and supervisors. Of the nearly 860 young workers who have been in the workforce for two to three years upon secondary school graduation interviewed, few were concerned about work ethics. The survey featured a scale of ''ethical judgement'' and ''ethical action tendency'' comprising hypothetical cases of normal work situations. People choosing ''ethically acceptable'' were given lower scores, meaning that they had low ethical standards and cared little about work ethics. Nearly 20 per cent of respondents had low scores, over 60 per cent had medium scores and 18 per cent had high scores. ''People who work under satisfactory conditions and have great interest in their jobs should respect their work and have good work ethics. It is important for students to think carefully before picking a career,'' Mrs Cheung said. To help young people become ''happy and ethical workers'', the ICAC's Education Office will release an ''Onward to 21 - Life and Work Guidance'' package next week. Findings of the surveys would be included in the package.
