As seen above, career cushioning has various benefits for your company while it also makes your employee feel safer. As a result, career cushioning is not something you can or should prevent, partly because you cannot control what employees do in their free time, and partly because you might not want to miss out on the effects that may benefit your company.
At the same time, you can try strategies that help retain workforce, encourage organizational citizenship, and assert job security. This way the employees more actively working on career cushioning have more incentive to stay with your Hungarian company.
