In this argument the author reaches the conclusion that employer should reward employee based on their performance rather than years of service. The basis for this recommendation is that rewarding employees on years of service will discourage their productivity in the long term. At first glance, the author's argument appears to be somewhat convincing, but further reflection reveals that it omits come important concerns that should be addressed to substantiate the argument. Deficiencies in this argument will be illustrated through following discussion. In the first place, author states that payment method based on performance is better than years of service by only presenting one disadvantage of the payment method based on years of service. This is not a logical argument as there is no evidence to show that reward the employee on their performance is better. It is possible that payment method based on employee performance has some disadvantages as the payment method based on years of service does. In the second place, the author assumes that salary payment can be based on employee performance and years of services are mutually exclusive alternatives and there is no room for middle ground. However, the author provides no reason for imposing either-or choice. Common sense tells us that adjusting both payment method together might be a better choice for employer. In conclusion, the author fails to provide adequate justification for proving payment method based on employee performance is better than years of service. As it stands, the reasoning does not constitute a logical argument in favor of the recommendation. If it included the items discussed above, instead of only showing one disadvantage of rewarding employees on years of services, the argument would have been more thorough and convincing. 老师，能帮我看看作文吗。我想不出第三点了。还有您能说一说怎么论证吗？
