How can the newspaper or social media post test guide ethical decisions?

"Making an ethical decision might come down to how you feel about the decision or to the newspaper or social media post test. The question to ask yourself is how the decision would make you feel if an objective reporter described the decision on the front page of a newspaper or via a social media post on Twitter or Facebook—all of which would be viewed by many, many people. Speaking of social media, it plays a pivotal role in ethical decision-making today, when people use the medium to share critical comments about friends as well as employers, business colleagues, and competitors. Should companies view employees’ social media pages on a regular basis, or is that information off-limits to employers?"
