The undue exposure of the intimacy of an employee, in his workplace, was already a reason for dispensing by just cause, such as the case of a nurse in Pernambuco who published, on his page of a social network, photos in which made jokes with his co-workers at the ICU (Intensive Treatment Unit), using the hospital uniform and working hours. Even with the entrance of a labor claim to reverse the context of the dispensation, the Superior Labor Court decided on behalf of the Pernambuco Hospital.

This quick access to personal information on social networks are causes that influence a process of selection to a workplace, until the cause of a justified dispensation.

Technology has caused great revolutions in the legal world. In particular, in the scope of work, the use of social networks has given a broad and rapid access to the information and the particular routine of each worker, which raises questions mainly about intimacy and freedom of expression.

Also, another issue is raised, of freedom of expression. The right of each one has their choices and opinions. Exemplifying, there was the case of a server of ITU (SP) prefecture server that urged in a post that the population should no longer vote in certain "pilantras" of incompetent administration, and as a result was disconnected from its position by the mayor of the city. The employee entered with labor and indemnifying action against the municipality and obtained a decision to his favor, as the comments concerned political facts known in the region.

common sense is the key to avoiding a good "headache", for both sides, employee and employer. It is difficult to separate professional and personal life, especially when exposed and with easy access to the Internet. The fact is that social networks can be beneficial or harmful by the user with this discernment.
