Omicron leading to global staff shortages

Omicron is having an impact on the global workforce. To try and tackle the problem in the US, health authorities have halved the recommended isolation period for people who test positive for COVID-19, but don't exhibit symptoms. Dr Sara Machado, health economist from the London School of Economics, looks at what measures could get people back to work, and which are unlikely to help. Also in the programme, China's foreign ministry has accused the United States of putting astronauts in danger by ignoring obligations under treaties on outer space. This programme is presented by Rahul Tandon and produced by Josh Thorpe and Susan Karanja.
