Omicron leading to global staff shortages

Available for over a year

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 nineteen, but don't exhibit symptoms. Dr Sara Machado, health economist from the London School of Economics, looks at what kinds of 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. In this context, the BBC's Jane Wakefield looks at the issue of space junk in an extended report. And finally, we look at the first film to earn over a billion dollars in the pandemic early. We ask film critic Caroline Front: is it a sign that audiences are ready to come back to the cinema? This programme is presented by Rahul Tandon and produced by Josh Thorpe and Susan Karanja.
