Interesting article from Nikkei. More people who are over 50 years old are changing jobs than before. The number doubled in the last three years. It used to be believed that the age limit for changing jobs was 35, but it is obviously not true now due to the serious shortage in the workforce. These skilled people are most wanted among construction companies and start-up businesses because they can work right away without training.
