Final answer:
Jenny must use an objective stance and be critical but fair while conveying negative feedback in the performance review.
Step-by-step explanation:
Jenny, as a sales manager preparing a performance review about one of her employees, must be careful about the characteristics of business writing. In this report, Jenny must use an objective stance, which means writing in a way that is free from bias, personal feelings, and emotional language. It's important for her to present factual statements and statistics to support her evaluation of the employee's performance.
Additionally, Jenny must aim to be critical but fair while conveying the negative feedback. She should avoid being impressionistic or merely nasty, and instead adopt a tone that is reliable and intelligent. By maintaining an objective and critical stance, she can provide constructive feedback to help the employee improve without being overly negative or demoralizing.
