I don’t know if it would be that effective- it’s clear this persons post is currently in the positive. It’s highly likely there are other people in positions where they can hire others who have contributed to keeping the position in the positive score range (or at least not so negative that you have to highlight it to see it). By making it more broad we can assume that a silent chunk of people upvoting it agree for their own companies and positions of power too, and those we can’t pull aside to ask who they work for.
