Regarding pre-employment screening, businesses must balance obtaining the needed information with maintaining personal privacy. Some employers, and many job candidates, consider social media checks to be an invasion of privacy.nnHowever, social media platforms are public forums, not private ones. Looking for personal information such as family size, religious beliefs, or sexual orientation is ethically dubious.nnBut, looking for hate speech, discriminatory practices, drug use, or other behaviors that could compromise a candidate's job performance or create a toxic or hostile workplace should be noted. So, there's a fine line between what you should and shouldn't look at while reviewing social media history. That's why using a third-party service that will only examine social media activity through those parameters is a good idea.
