This week the roads running to the ports in the South East of England turned into a lorry park when continental Europe blocked arrivals from the UK– so Business Weekly takes look at trade and the travails of the global shipping industry. How has this vital sector fared during the pandemic? As France bans discrimination against regional accents we’ll ask whether the way you talk really affects your job pospects. The Chief Executive of the Royal Albert Hall tells us how this historical London venue is coping without box office sales - and we'll hear from the entrepreneurs who set up new businesses in the middle of a pandemic.

Business Weekly is presented by Lucy Burton and produced by Clare Williamson.

This year has seen our cities coming under pressure as they struggled to withstand the impact of the coronavirus. City centres were deserted as shops shut and people stayed away. But in some city streets there was a new community spirit as people faced the pandemic together and supported neighbours they'd never met before. In this programme, Tamasin Ford investigates what the future could be for our cities, and asks how they need to change if they are to survive, and even flourish. We hear from architect Siri Zanelli; the mayor of Bristol in the south-west of England, Marvin Rees; transport planner Susan Claris; Singapore-based Lauren Sorkin, the head of the Resilient Cities network; Liu Qian of Greenpeace in Beijing, and Rosamund Kissi-Debrah who has been a campaigner for better air quality since the death of her daughter from asthma in 2013.

Talks between the UK and the EU on a post-Brexit trade agreement continued during the night, but a deal is expected to be unveiled on Thursday. Negotiators in Brussels are said to be trying to finalise details on fishing quotas, which have proved an obstacle to an agreement during months of talks. On the programme we'll hear from Sally Jones, Brexit lead at Ernst and Young, Charles Grant at the Centre for European Reform, as well as the BBC's Political Correspondent Rob Watson.

How the shipping industry has fared in 2020. Ed Butler speaks to Lars Jensen from SeaIntelligence Consulting about the ups and downs of the shipping industry during the pandemic, in a year that has seen a collapse in economic activity, but a boom in online shopping. And Bridget Rosewell, commissioner for the independent National Infrastructure Commission in the UK, explains why disruption to supply chains could cause businesses to rethink the way they ship goods around the world.

Unilever in New Zealand is the latest firm to trial a 4-day week without cutting pay. Manuela Saragosa speaks to Paddy Gamble, the CEO of Perpetual Guardian which manages trusts, wills and estate planning. A couple of years ago they put their 240 staff on a four-day week but paid them for five. He says productivity has gone up since they introduced it. Charlotte Lockhart runs a global campaign for a 4-day week and she says its easy to do and its doesn't cost very much. But Marc Effron, president of The Talent Strategy Group, a global human resource management consultancy firm says a four day week doesn't actually improve productivity.

How do brands strike the right tone in their Christmas adverts when many consumers have taken a financial hit? Elizabeth Hotson goes on an advertising odyssey and talks to Sarah Traverso, Group Director of Integrated Marketing and Content for Coca-Cola in the US, a company so central to Christmas advertising that some think Coca Cola invented Santa Claus. A myth quickly debunked by Ann Christine Diaz, the creativity editor at Advertising Age. What is the secret behind a successful Christmas campaign? A question for Simon Lloyd from DentsuMB, who was until recently the creative director of the advertising agency behind the John Lewis department store Christmas adverts. Global advertising spend is expected to contract by 10% ( $63bn) this year and with people spending so much time at home during the pandemic, the focus has gone to online advertising and social media, as James McDonald, Head of Data at the World Advertising Research Center, explains.

On Business Weekly this week, we examine the potential big trouble for Big Tech. Regulatory bodies around the world are looking to tighten the rules that govern the digital world. Concerned by issues relating to both the web content and the business conduct of some of the big technology companies, legislators from the US to the EU are trying to re-write the digital laws. We look at what this could mean in practice for Silicon Valley. We also look at dry ice – how it works and the important role it will carry out in the distribution of the Pfizer Covid-19 vaccine, as well as the possible implications that could have for drinks industry. Plus, while Zoom business meetings are all the rage now, how long before virtual reality takes them to the next level? And we discuss the joy of traditional Christmas correspondence and find out why young people are starting to send greetings cards again. Business Weekly is presented by Lucy Burton and produced by Matthew Davies.

America’s cannabis industry is worth tens of billions of dollar and it generates tax revenues and jobs. But it is barred from accessing most financial services. This is because, while legal in an increasing number US states, cannabis remains illegal at a federal level. We hear what it’s like running a cannabis business from Ken Churchill of the West Coast Cannabis Club in California. Emily Dufton, author of Grass Roots: The Rise and Fall and Rise of Marijuana in America, explains how the US went from "Just Say No" in the 1980s to yes now. And Robert Hoban, a lawyer who specialises in cannabis, explains why two currently empty Georgia Senate seats could determine whether the Biden administration can fulfil its pledge to decriminalise cannabis.

Why US regulators want to break up the social media giant. The US Federal Trade Commission (FTC) and dozens of US states are arguing that Facebook is a monopoly that harms consumers. Ed Butler speaks to tech and anti-trust researcher Dina Srinivasan about why data privacy is at the centre of the arguments over Facebook's monopoly power. Former FTC chairman Bill Kovacic explains why breaking up the social media giant is still a distant possibility. And the BBC's technology correspondent Rory Cellan-Jones discusses the rising anti-tech sentiment among both US and European regulators.

Could virtual offices provide an alternative to endless Zoom calls? Ed Bulter speaks to Jeremy Bailenson, director of Stanford University's Virtual Human Interaction Lab, about the phenomenon of 'Zoom fatigue', and why virtual reality could provide a solution.

Ed tries out a meeting in virtual reality with Anand Agarawala, CEO of the VR platform Spatial. And Marc Bena from PwC explains why interest in virtual meetings is growing among businesses.

Artificial intelligence is increasingly part of our daily lives - in health, in transport, entertainment and much more - but how many of us actually trust the algorithms that drive it? Rolls-Royce says it’s now developed a system, called the Aletheia framework, that gives IT engineers in any sector a way of testing whether their AI systems are making decisions that are safe and trustworthy. The aerospace company says it's making the framework available for free to all. Manuela Saragosa speaks to Caroline Gorski from Rolls-Royce who helped develop the Aletheia framework. She also speaks about AI's trust issues with Dame Wendy Hall, Professor of Computer Science at the University of Southampton in the UK and Chair of the Ada Lovelace Institute. Plus Pag Miles from the global recruitment company Alexander Mann Solutions, explains how the Aletheia framework might help his industry which is increasingly relying on AI to select and match candidates to jobs.

Negotiators from the UK and EU are to begin a new push to reach agreement on post-Brexit trade after both sides agreed "to go the extra mile". A UK source said the "process still has some legs" but Boris Johnson has warned a no-deal is the "most likely" outcome. Sophie Pornschlegel, a senior policy analyst at the European Policy Centre, explains how much room there may be in Brussels' position, while the BBC's Rob Watson talks through what will be needed to get any deal over the line in the UK parliament before the 31st. And we'll hear from a UK coffee exporter, Dan Webber of Chimney Fire Coffee in Surrey, about what the prolonged uncertainty means for his business.
