The important and current matter concerning the relation between new technologies and the reality of labor has attracted the interest of academic researchers in the last decades. As of the second half of the 20th century, the third technological revolution has brought so many changes into labor relations that its issues became some of the most investigated themes in the areas of sociology, economy and, obviously, labor law. Moreover, in the first decades of the 21st century, this matter has become all the more relevant as a result of the deeper transformations that new technologies have promoted in social, economic and labor relations. The fourth technological or industrial revolution has shown signs of emergence in the first years of this century. The challenges of some of these deep technological and social innovations are approached in the present academic work, entitled Social and Labor Relations and New Technologies.
