The context indicates and implies an implies an example. Jim is being compared to you as a worker.
"Such/as" in option A is used to demonstrate an example or a similar kind of instance. This is correct as it compares Jim and you.
"So/that" in option B is incorrect as it is used to introduce a clause of purpose. This is not the requirement of the context.
"Such/that" in option C is used to express purpose or result. However, here we just want to demonstrate a comparison.
"More/than" in option D is used to indicate a thing of greater value importance. However, here the comparison is indicative to the detriment of the subject.
Therefore, option A is correct.
