Write an essay (at least 6 paragraphs) in which you sum up what you believe to be the major or biggest obstacle(s) or barrier(s) to communication on the job/in the workplace.
Please do not simply edit the diagnostic essay and submit it again. You are required to do a serious rewrite using the feedback your instructor gave you; this may mean starting the essay over completely if you did not do well on the diagnostic essay.
One change from the diagnostic (aside from the modification of the topic) is this: you are now writing a persuasive essay, using argumentative technique. To do this well, you must include consideration of a counteragument and offer a refutation for it. This MUST be included somewhere in the essay, either as a separate (6th) paragraph, or wherever you find suitable.
