We are living through a fundamental transformation in the way we work. Automation and 'thinking machines' are changing the skills workers need, while demographic changes promise a talent shortage, longer lifespans, and other significant shifts that will affect the workplace. These changes raise huge organizational and human resource challenges at a time when business leaders are already wrestling with unprecedented risks, disruption and political and societal upheaval. To help you think about what this means for your business and your career, we developed scenarios for the future that reflect the various forces in the market. We call them the four worlds of work. You can use these scenarios to kickstart your thinking about steps you can take now.
