  • SESHA | Make Safety Training Stick: How to guarantee your employees will remember and apply what they learn

    Managers and the organizations they lead consistently put time and effort into training their teams, but often important business metrics don’t move as a result. Team members don’t recall and apply learning at the right time. Recordable rates say high, employee engagement stays low, and turnover skyrockets. But there is hope on the horizon. In recent years learning scientists have made tremendous progress in understanding how people learn and apply new knowledge at work. These new methods are easy for managers to utilize, and they and can impact the way we think about teaching any topic – especially safety. In this webinar you’ll learn some easy-to-apply methods that will help you employees learn, remember, and apply knowledge exactly when they need it.
