ARGUMENT 241
241. The following appeared in a memo at the XYZ company.
"When XYZ lays off employees, it pays Delany Personnel Firm to offer those employees assistance in creating resumés and developing interviewing skills, if they so desire. Laid-off employees have benefited greatly from Delany's services: last year those who used Delany found jobs much more quickly than did those who did not. Recently, it has been proposed that we use the less-expensive Walsh Personnel Firm in place of Delany. This would be a mistake because eight years ago, when XYZ was using Walsh, only half of the workers we laid off at that time found jobs within a year. Moreover, Delany is clearly superior, as evidenced by its bigger staff and larger number of branch offices. After all, last year Delany's clients took an average of six months to find jobs, whereas Walsh's clients took nine."
Comparing two personnel Firms, the author concludes that Delaney company is superior to the Walsh Personnel Firm and the XYZ company should not change their choice, for the reason that the laid off workers who have been trained by the formers had a larger ratio to be employed and taken a shorter time to find a job. However, the conclusion relied on a series of unproven assumptions.
To begin with, the argument assumes that the Delaney Company really benefits those laid-off workers. Yet, the mere fact that last year those who used Delany found jobs much more quickly than did those who did not hardly suffices to infer any such effect among workers. Without more evidence about two groups of workers, it is just as likely that there is no difference between the both group, because it is probably that trained group originally have their advantages over the other, such as the level of educated, working experience or more productive etc.
Even assuming the Delaney Company’s works really benefits the workers, the author does not provide enough evidence to compare the two company’s effectiveness. The author only tell us half of the workers we laid off at that time found jobs within a year, without mentioning what the proportion of workers who have been assisted by the Delany's service.
Besides, the author does not provide more information about Walsh's clients. The Delany’s clients may encounter more chances of employment than the Walsh’s Clients. Or else, Delany’s clients may also be more productive than the Walsh’s. So, without ruling out these or other reasons that the Delany’s workers are more easily to find a job, the author cannot convince me that the Delany Company have a better effect.
And the bigger staff and larger number of branch offices which belongs to the Delany cannot justify its advantages, either. On the contrary, that may reflect the Delany’s low efficiency instead of powerful background. Because the author fails to corroborate the Delany make best use of their resource, whether human labor or materials, and the average productiveness of their employee is higher. Thereby Delany Company may not be better than the Walsh Company.
Even assuming the Delany Company really does better than the Walsh, the choosing the Walsh Company may not be unreasonable, because the Walsh may charge a lower price than Delany. Compared with the other, the former may generate more benefits per dollar than the latter.
In sum, the argument relies on what might amounts to incomparable cases, as well as the shortage of the further information about the two companies. To strengthen the argument, the author should show us comparison between the employments of workers which have been trained by the two companies under the same conditions, and the clear evidence about the advantages of the Delany companies over the Walsh Company. Even with these additional evidences, in order to evaluate the two companies, we have to know the prices of the services and whether it really is really in accordance with the XYZ Company’s need. |
