The Bottom Line

What does it take to drill oil out of the ground and then refine it into petrol, jet fuel or other petrochemical products? The world currently uses about a hundred million barrels of oil a day. However, the daily flow has been affected by the closure of the Strait of Hormuz. A fifth of the global supply normally passes through the waterway in tanker ships, but it's been blocked since the end of February 2026. How has the industry adapted?

The 2026 London Marathon saw new world record times set in both the men's and women's events. Eyes weren't just on the winning athletes but also on the Adidas trainers they were wearing. So what goes into designing and making a pair of trainers and why have some of them become so expensive to buy? Global sales for trainers are in the tens of billions of dollars with hundreds of new styles being produced every year. How does the industry keep up with demand and stay on trend? Giant companies like Nike and Adidas, who dominated the industry for decades, can no longer take anything for granted. Newer brands like On and Hoka have managed to break through and are shaking things up. How have they managed to do it? Evan Davis gets some insights and answers from people who work in the industry.

From smartphones to trainers, confectionary and cleaning products, we live in a culture of constant updates. Companies reformulate, redesign and refresh their products in a continuous race to stay ahead. But how are those decisions made? What counts as meaningful improvement and how much is designed to make last year’s version feel old? Evan Davis and guests discuss how products evolve and why standing still is the fastest way to fall behind.
Guests:
Tom Moody, Senior Vice President and Managing Director, P&G (Proctor & Gamble) Northern Europe
Dr Garry Moppett, Senior Director of Research & Development at Mars

Across our professional careers, many of us will come into contact with a difficult colleague or hard-to-please superior. But what happens when difficult behaviour crosses over into bullying at work? What effect does this have, not only on our wellbeing, but on our workplace as a whole?
Evidence suggests that bullying may be on the rise in the UK. A 2025 survey of British workers conducted by ACAS (Advisory, Conciliation and Arbitration Service) found that 44% of respondents had experienced conflict at work in the last 12 months. And on the global stage, the resurgence of ‘strong man’ leadership has reignited a debate: does bullying behaviour get you what you want?
Evan and the panel look at what workplace bullying is, when and why bullying can occur, and the steps individuals and organisations can take to tackle this behaviour in the workplace.

Jason Warner, Managing Director (UK and EMEA) at SBS
