On Business Weekly, we look at the problems faced by companies affected by the spread of the Omicron variant of Covid-19. Are staff shortages just a blip or could they be more long term? Professor Joshua Hausman at the University of Michigan gives us his view. Plus, we look at efforts being made in the textile industry to move away from “fast fashion" using traditional, slow and more sustainable methods. Also, it’s 20 years since the schoolboy wizard Harry Potter first appeared on movie screens; which businesses are still feeling the marketing magic? And we shake and stir with some of the world’s top mixologists to find out about the trends in cocktails for 2022. Business Weekly is presented by Matthew Davies and produced by Clare Williamson.
