Topics to be discussed: Diversity is not marketing - Internal campaigns and, especially, social networks already follow a fixed calendar of campaigns throughout the year. However, much more than following the trend of the moment, it is essential that diversity leaves the traditional choice of promotional images with various ethnic groups and is present in everyday practice. In this panel, the speakers will debate the ways for representativeness to become a growing reality in all areas of the company.
