How social network sites (SNS) have changed the employer-employee relationship and what are the next challenges for human resource (HR)?

Business people are increasingly using social network sites (SNS) through corporate platforms or open websites such as Twitter, Linkedln or Facebook. Because it is a recent phenomenon, the potentialities, benefits and risks of such tools have not yet been properly addressed inside organizations. SNS have been used by different members of society, including people of all ages and social classes. Human resource (HR) refers to the practices and policies adopted by companies to carry out the personnel aspects of the work, but some organizations are reluctant to permit SNS access within workplace boundaries. Currently, it is imperative to recognize SNS as an extension of people's social activities and, instead of restricting their use, companies should appreciate the benefits arisen from them. The objective of this essay is to discuss how HR activities are traditionally performed, the changes caused by the emergence of SNS and the new challenges. Thus, it may be useful for HR practitioners as it highlights how key HR activities are being affected by the emergence of SNS. Given the new challenges, HR professionals should use SNS as a complement of their activities, developing policies of use and monitoring the workforce online behavior.
