Argument186: 478 words 30 minutes
The following is a recommendation from the director of personnel to the president of Professional Printing Company.
'In a recent telephone survey of automobile factory workers, older employees were less likely to report that having a supervisor present increases their productivity. Among workers aged 18 to 29, 27 percent said that they are more productive in the presence of their immediate supervisor, compared to 12 percent for those aged 30 or over, and only 8 percent for those aged 50 or over. Clearly, if our printing company hires mainly older employees, we will increase productivity and save money because of the reduced need for supervisors.'
In this argument, the arguer suggests that Professional Printing Company hire older workers to increase productivity and save money. To bolster the suggestion, the arguer provides the result of a survey which indicates that older employees are less likely to increase their productivity under supervisions than the younger ones. At first glance, this argument seems to be reasonable. However, a meticulous scrutiny would reveal how untenable this argument is.
A threshold problem with this argument is that the arguer takes for granted and without justification that the younger employees without justification will be less productive than the older workers. Although more younger people reported that they will increase their productivity if a supervisor is present, that does not necessarily mean that without supervision, they will do a worse job than the old employees .As a matter of fact, for the reason that young peoples are more active, energic, and enthusiastic, they are likely to finish the job better than the old ones even if without supervision. If the arguer is not able to prove that the older workers do a more productive job than younger ones without supervision, the suggestion is doubtful.
Another problem with this argument is that the survey is open to question. Destitute of sampling a sufficient number and manifesting any sign of such procedures for random sampling across the whole gamut of employees, the survey is not representative to reflect the general attitude of the employees. According to the arguer, the survey is conducted through telephones. Consequently, employees without a telephone is not included in the survey .Besides, the employees just reported that whether they would be more productive un supervision. That does not mean they will indeed act so. Maybe the younger workers are not as familiar as the older ones with the job and therefore they just make assumptions.
Last but not least, another defect that saps the logic of this argument is that even if we admit that the survey in reliable and younger employees will indeed be more productive under supervision, we still lack evidence to believe that suggestion is bound to save money. It is quite possible that the older employees require much higher salaries on account of their rich experiences and much more welfares have to be provided to older workers. Besides, there is no evidence indicating that the company has supervisors now. If so, the measure is not able to help save money as there are no supervisors to reduce.
To sum up, this argument lacks credibility for the reason that the arguer is incapable of providing adequate evidence to what he/she maintains. To strengthen the argument, the arguer would have to provide more information about the younger works productivity without supervision and older employees' productivity as well. To better access this argument, we have to know more details about the survey and the company's condition now. |
