FORTUNE - LinkedIn CEO Ryan Roslansky revealed how the end of 2021 brought on a surge of professionals jumping ship to new employers following a period of great uncertainty which he refers to as the Great Reshuffle. The surge in job-hopping was mainly driven by Gen Z and millennials, who moved at a record pace in what represented an unprecedented shift in the advertising industry. While Roslansky’s findings specifically refer to the advertising industry, it serves as a warning to every sector that retaining Gen Z talent is not as straightforward as it once was with previous generations.
