Young people often wonder at the large number of employers who do not respond to their application for jobs. They say that despite enclosing return envelopes they hear nothing at all or, at best, an impersonal note is sent declaring that the post for which they applied has been filled. Applicants often developed the suspicion that vacancies are earmarked (指定) for friends and relatives and that advertisements are only put out to avert (转移) this accusation. Many of them tire of writing around and feel that if only they could obtain an interview with the right person their application would meet with success.
Not to acknowledge applicants" letters is impolite and there seems little excuse for this. Yet even sending brief replies to the many who apply takes much time and money. That so-called return envelope may not have been stamped by the sender, and a hard-pressed office manager may be reluctant to send off long letters of explanation to disappointed job-hunters. A brief note is all that can be managed and even that depends on the policy of the firm. But this difficulty is reasonably easy to remove with a little goodwill. What is the chief reason for a manager not to acknowledge applicants" letters
A．Sending letters of acknowledgement takes much time and money. B．He finds the return envelopes unstamped. C．He does not want to disappoint the applicants. D．He is acting on the policy of the firm.
