Technological revolutions have brought about dramatic changes in the world and in the ways people live, think, behave and feel. The purpose of the present study is to understand how the arrival of cell phones has affected the ways employees in the contemporary labor market live their private and professional lives. For this purpose, professionals who have children and whose cell phone accounts are paid for by their companies were interviewed. All of them lived and worked in Rio de Janeiro. Their answers showed that there is no frontier between their professional and private lives; cell phone use makes their working and professional lives mingle. In addition, the results revealed that the lives of those who took part in the present study have become more agile due to the fact they can both work and contact their homes and family at any time, no matter where they are. However, these professionals, who can also be easily reached by means of their cell phones, feel that they have to be available to their employers all the time in order to quickly solve their daily demands by phone. The cell phone, in the same way as the computer and the e-mail, has become a working tool. The interviewees admitted they could not imagine their daily lives without those tools. The interviews also showed that new habits have been created as a result of the constant use of those tools. Among these new habits are the administration of home and family from any distance and the possibility of work remotely.
