In a crazy world, how do we get better leaders?  This is the boardroom, unplugged. — Whether starting out, or a seasoned leader, you face a world we’ve never seen before - the future of work, politics, technology and society is harder to predict than ever. So how do we survive the uncertainty and thrive in complexity? The successful leaders of the future will need a different set of skills and come from a broader range of backgrounds. This is for you.  We’re by leaders, for leaders - human stories, messy realities, tips and tricks to use today… not corporate talking points or retrospective perfection.

Ex John Lewis Boss: Why The Best Leaders Are Impossible to Read | Sharon White

Ex John Lewis Boss: Why The Best Leaders Are Impossible to Read | Sharon White
Welcome to What We Don't Know with Matt Brittin & Hayaatun Sillem. The show about better leadership in a truly chaotic world. Across the series, episodes are joined a range of other leading figures, bringing different perspectives to each conversation. Subscribe to not miss an episode! ▶️ ⚡️ Powered by Boxlight.io https://www.boxlight.io/ ------ This week, Hayaatun is joined by Jimmy McLoughlin OBE, host of ⁨@jimmysjobs⁩ , to welcome Baroness Sharon White. Sharon White traces her journey from a working-class East London childhood — daughter of Windrush generation parents who left school at 11 and 14 — through 26 years as one of Whitehall's most senior but deliberately invisible civil servants, to leading OFCOM and later the John Lewis Partnership through COVID and financial turbulence. She shares why being impossible to read became a strategic asset, how the insider/outsider experience of growing up as a minority shaped her willingness to hold unpopular positions, and why she believes the problems facing political leaders today are categorically harder than a generation ago. She reflects on what it takes to lead 80,000 partners through a democratic business structure unlike anything in the private sector, why a reluctant regulator is a better regulator, and how to tell the difference between noise and what's actually real when everything feels urgent. She also discusses building crisis-ready teams before the crisis hits, the leadership skill she thinks nobody talks about enough — and what her teenage son taught her about inclusion.

At 26 he helped develop the Truth and Reconciliation Commission law and became its executive secretary under Archbishop Tutu, sharing leadership lessons about preserving opponents’ dignity and Mandela’s openness to hearing testimony about ANC abuses. He discusses empathy and Ubuntu as foundations for resilient societies, the role of information ecosystems and economic breakdown in modern polarization, and ways to embed Ubuntu in organizational culture. He describes the personal toll of trauma, later scaling transitional justice support globally by offering comparative experience rather than prescriptions, and founding London’s Conduit to convene coalitions tackling complex challenges like UK flooding.

Why Great Leaders Stop Trying To Be Busy
Time Management for Leaders: The 4Ds, Being Present, and Making Busy Work Matter Welcome to What We Don't Know with Matt Brittin & Hayaatun Sillem. The show about better leadership in a truly chaotic world. Across the series, episodes are hosted by Matt and Hayaatun as well as a range of other leading figures, bringing different perspectives to each conversation. Subscribe to not miss an episode! ▶️ ⚡️ Powered by Boxlight.io https://www.boxlight.io/ Hayaatun and Matt explore why leaders obsess over time and how choices, not sheer scarcity, shape outcomes. They discuss practical tools for overload, including Hayaatun’s “4Ds” (delegate, delay, drop, do), getting worries out of your head and into reliable systems (quadrant to-do lists, calendars, colored pens), and tackling the scariest task first to reduce stress. Hayaatun shares formative lessons from the high-pressure pace of the House of Commons and the value of trusted teamwork, while Matt reflects on preparing for leadership “set pieces,” using low-meeting days, processing time (commutes), and block time for deep work. They cover signals leaders send through calendars, the importance of hiring and tough conversations, meeting waste, and why sleep matters despite occasional crunches. 00:00 Zombie Consultants Intro 00:33 Time Choices Question 01:32 Meet The Hosts 02:09 Leader Time Signals 04:30 Four Ds Framework 06:10 Drop And Do 08:30 Quadrant List System 12:07 House Of Commons Pace 16:40 Fast Drafting Lesson 20:02 Prepared CEO Style 22:54 Safety Valves And Fridays 24:47 Calendar As Choices 27:02 Sauna Politician Aside 27:49 PhD Roots Of Time 29:01 Overwhelm And Fear 29:41 Do Scary Thing First 30:52 PhD Stress Triggers 32:20 Emotions As Data 34:19 Peak Hours Block Time 35:23 Travel Energy Management 37:42 Busy Leader Signals 40:48 What Leaders Cant Delegate 43:53 Chunk Time Strategy 46:16 Calendar And Team Alignment 51:15 Time Audits And Meetings 53:56 Sleep And Crunch Times 56:36 Key Takeaways On Time Management Credits: Producer: Sunny Winter Producer: Thuy Dong Producer: Jimmy McLoughlin OBE Post Producer: Ben Alexander Kippen Learn more about your ad choices.
