Q. Can I use social networking websites to screen potential job    candidates?  
    Social networking websites such as Facebook, Twitter and    LinkedIn provide a wealth of information to employers seeking    to learn more about potential job candidates during the    recruitment process. With that abundant amount of information,    however, employers may gain knowledge that cannot be used in    making employment determinations and could result in legal    repercussions.  
    For example, an individual's online profile may show previous    job experiences, educational background, or connections with    other employees. On the other hand, such websites may reveal an    individual's sexual orientation, disability, age, marital    status and health issues. New Jersey's law against    discrimination, as well as various federal statutes, prohibit    employers from engaging in discrimination based on these and    other characteristics when interviewing, recruiting, hiring, or    promoting employees. Once the employer gains information about    these traits while viewing an individual's social networking    profile, it may prove impossible to separate that information    from consideration during the hiring process.  
    How do employers take advantage of the vast amount of helpful    information available through online social networking websites    without transgressing the law and creating an opportunity for    litigation? One potential solution is to implement a    "screening" process to keep potentially problematic information    from reaching those responsible for hiring decisions.  
    By designating one individual or a third party to conduct    online searches of prospective employees, any "tainted"    information can be removed from the search results. A separate    individual or group could then interview candidates and make    the ultimate hiring determination, thus insulating the process    from the infected information. Employers should implement a    company policy regarding how such information is gathered and    reviewed during the employment process to avoid practices that    could be viewed as discriminatory.  
    Because each business situation is unique, employers should    consult with an attorney about drafting such a policy to meet    the individual needs of his or her particular business.
