We live in an era when a very specific phenomenon is occuring. People from the so-called Baby Boomer generation (or post-war generation) are still actively participating in the labor market and at same time Generation Y is already reaching its most productive age. Thus, up to four generations can meet at the same workplace at the same time. Each of these generations experienced a different period, was influenced by different events in the world, different technological progress, shaped by different social influences. As a result, each generation has different characteristics and values. This is an unprecedented situation that brings many unexpected challenges, potential conflicts or clashes. If such a situation is not managed, an unpleasant work environment can be created, employees may experience more stress or in the worst cases termination of an employment.
