Lack of interaction between age groups is hampering workplace productivity, according to a recent investigation by LinkedIn. The research revealed that only one in five members of generation Z – those under 27 – had spoken to anyone over 50 at work in the past year. While 44% of over 55s had avoided conversations with their youngest colleagues. But while the problem is most acute between Gens Z and X, it also exists across the age spectrum, with 17% of employees admitting they did not know how to approach colleagues outside their age group.LinkedIn’s UK manager Janine Chamberlin, quoted on the website of B2B brand consultants Raconteur, said: It shows there isn’t enough collaboration and sharing of skills between different generations.This will result in a loss of knowledge that exists among the eldest workers and reduces the number of opportunities for the youngest to learn.”
