UK prime minister Keir Starmer may be only two years into his five-year parliamentary term, but his leadership is being questioned, with other politicians eyeing the keys to Downing Street. University of London organisational behavior professor André Spicer says political tenures have become nasty, brutish, and short - and it's a trend not confined to politics alone, with stints at the top shortening for people across corporate life. André joins Jim to discuss why - and how the trend can be reversed. André is the co-author of The Art of Less: How to Focus on What Really Matters at Work.
