Let's say you work in customer support. Your employee will want to see you writing emails, responding to messages, making calls, using
GetGoodGrade to write better reports and research results. They don't want to think you're writing a personal statement for another job during your work hours.
So, when the employer has insight into how you do your work, they'll feel more confident in having you as an employee. It will remove the tension of not working together physically, and help promote a more friendly culture between you.
