第5题：Ask any employee at an level in any company what they dislike about their job and somewhere on the list you will find a complaint about the system of performance appraisals. It does seem strange that an idea which was supposed to benefit both individuals and the company should be so universally disliked, but the staff appraisal is now one of the biggest causes of dissatisfaction at work. In the United States there have even been cases of unhappy workers taking their employers to court over appraisal interviews. It is in a company’s interest to combat this situation, but, before reversing the appraisal’s negative associations, an organization needs to pinpoint the underlying reasons which have contributed to them. Problems with appraisals can fall into two main areas--those arising from the scheme itself and those arising from the implementation and understanding of that scheme. Naturally it is easier to tackle those in the former category; indeed, some companies have developed schemes following legal guidelines. These guidelines suggest that a successful scheme should have a clear appeal process, that any negative feedback should be accompanied by "evidence" such as dates, times and outcomes and that, most importantly, ratings should reflect specific measurable elements of the job requirements. It is not always necessary to resort to legal advice however. Some changes to current schemes are simply a matter of logiC、For instance, if employees are constantly encouraged to work in teams and to assume joint responsibility for their successes and failures, it makes little sense for the appraisals to focus on individuals, as this may lead to resentments and create divisions within the group. It is possible, and in some cases more suitable, to arrange appraisals where performance is rated for the group. Staff also need to be educated about the best way to approach appraisals. Managers often find that they are uncomfortable being asked to take on a more supportive role than they are used to without having had any training. Those being appraised may see it as a chance to air their grievances and highlight the company’s failings rather than consider their own role.Both parties view the process as a necessary evil, to be gone through once or twice a year, and then forgotten about. The importance given to the appraisal stems from the fact that, despite all the talk of the interview being a chance for management and employees to come together and exchange ideas, set joint targets and improve the way decisions are reached, the reality is that they are often nothing more than the pretext on which pay rises are given, or not given. Pay is, of course, a subject that always leads to problems. Given the problems associated with staff appraisals, why is it that, with no legal requirement, companies continue to run them The answer is simple, it is impossible to manage something you know nothing about.As any Human Resources manager can tell you, the best way to learn about someone is to talk to them.Effective people management relies on knowledge and appraisals are still the best way to build up that bank of knowledge. How are personal appraisals important for companies [A] They help HR managers to talk to staff. [B] They provide the best way to build new targets. [C] They help the company meet legal requirements. [D] They provide valuable information to the employer.
