The purpose of this paper is to explore the differences between people through generational analysis based on birth years. The intergenerational approach, which has now gone viral, highlights the changes in mindsets and behaviors that have occurred over time and that need to be taken into account in order to better understand people. Highlighting the differences between Baby Boomers and Generation Z, two contemporary generations at the extremes, we understand how people change over time, enduring the clear impact of technological, political and social changes on the work environment and social relationships. The intergenerational approach reveals the incompatibilities between people of different generations but also the need to adapt new ways of communication and management that take into account the differences as well as the common characteristics of the two mentioned generations, Baby Boomers and Generation Z.
