请大家帮我看一下我写的argument

At X company,workers who bring their own lunch from home are generally more productive than workers who purchase lunch at the company's cafeteria.Therefore,in order to enhance overall worker productivity,and in turn profits,the company's cafeteria should offer the same types of food that workers bring from home.

Response:

Based on the fact that workers who bring lunch to work are generally more productive than workers who purchase lunch at the company’s cafeteria,the author concludes that the company could enhance workers’ producitivity and in turn profits by offering the same kinds of food that workers bring from home.The author assumes that the criteria of lunch food is responsible for the workers’ elevated producitivity ,however,close scrutinity of the evidence reveals that it does not lend strong support to the author’s recommendation.

To begin with,the author does not specify whether the company’s cafeteria offers the same sort of food as those workers bring from home.If both are the same,then the author’s recommendation of changing the food of the cafeteria  amounts to invalid conjecture.

Secondly,given that the workers bring different kinds of food,the author unfairly assumes that the lunch food is the true cause of the worker’s higher producitivity.Mere correlation between the lunch food and improved productivity does not suffice a cause-and-effect relationship.It is entirely possible that the workers’ improved productivity is due to factors unrelated to the lunch food.If this is the case,then the author cannot justify that offering the same kind of food as that workers bring from home  will promote the workers’ overall producitivity.

Moreover,the author assumes that the proposed change of lunch food is necessary to enhance workers’ productivity.The author must consider and rule out alternative means that may be  more effective than the change of lunch food.Perhaps any improvements in the workers’ working procedure and more effective cooperation among staff members will promote the workers’ productivity in a greater extent.Unless the author rules out those alternative possibilities,I cannot accept the author’s recommendation.

Finally,the author’s argument relies on the unproven assumption that the proposed change of lunch food suffices the improved productivity of the company’s workers.Perhaps diversifying the kind of food the company’s cafeteria provides is also needed to ensure that workers will not be soon tired of the food ,which might somewhat in turn influence the workers’ interest in their work .Unless the author provide clear evidence that providing the same kind of food those workers bring from home  is the only alternative way to improve the workers’ productivity,the author’s recommendation is merely invalid and oversimplified.

In sum,the author bases his recommendation on a series of unproven assumptions.To bolster his recommendation.the author should provide better evidence.perhaps in the form of staff surveys,that those workers’ enhanced productivity is in a large extent the result of their lunch food that is brought from home.Moreover,the author must specify that the proposed change of lunch food is necessary to improve the productivity of the entire workforce.Unless the author does all this. I remain reserved about the author’s recommendation.
