Encouraging staff to use social networks has its positives to improve communication. While formal tools such as portals, discussion pages etc do technically support the same, social networks remove/reduce the formal working environment barrier. So this support more honest communication between employees and helps to build informal relationships outside the formal structure. It also makes sharing of information easier. In large organisations, the structure between teams (local and international) might hinder quick information access which social networks can support especially in the case of crisises or issues. Employees can learn of adversities in other parts of the companies helping them to react quicker. In an international environment where teams are working with minimal physical contact, social networks can play a huge role to humanise those relationships which could lead to a more harmonious and productive environment.
