The case explores how the UK Metropolitan police, working with the Girls’ Network, piloted a reverse mentoring programme for six months in 2021. Three senior officers were mentored by a trio of teenage girls from disadvantaged London boroughs. The aim of the programme was to address falling trust in the police by creating more understanding and empathy in the mentees for the issues facing the communities where the mentors lived, and to give the mentors more confidence from the experience of representing their communities. Each mentor–mentee pair focused on a specific policing issue that was relevant to the mentor’s neighbourhood: knife crime, domestic abuse or social inequality. Through the process, the senior Met police officers gained a deeper understanding of the challenges in the communities they served. Now that the pilot had been completed, the Met faced a decision point. Should the programme be spread further through the Met?Through reading and discussing the case, students are expected to explore the importance of empathy in the workplace and how reverse mentoring, when having the right support and overall intent, could be used in organisations.\u0000\u0000\u0000Complexity academic level\u0000This case is appropriate for university management courses.

The authors have made use of newspaper articles and published articles written by journalists and experts, which are available in the public domain.\u0000\u0000\u0000Case overview/synopsis\u0000This case discusses the hurdles faced by Netflix in India. Netflix experienced rapid growth ever since its entry into the Indian over-the-top (OTT) sector. The aggressive pricing strategies by OTT competitors put Netflix in a defensive position in India. Netflix introduced the low-priced mobile-only plan to attract price-sensitive Indian consumers. However, this was not sufficient. Netflix was forced to reduce the price of all its plans in December 2021. The dilemma faced by Reed Hastings (Founder and Co-CEO, Netflix) was whether the revised price was low enough to hold on to existing subscribers and attract new subscribers in India. Netflix was caught between the rock and the hard place in its pursuit to achieve its target of achieving 100 million subscribers from India versus continuing its skimming-pricing strategy. This case highlights the compound challenges of low household income in India and high-income inequality resulting in a lower available market for multinational service providers such as Netflix. The pricing plans and features of OTT competitors in India have also been discussed in sufficient depth to facilitate analysis and classroom discussion by the target audience.\u0000\u0000\u0000Complexity academic level\u0000Undergraduate students studying marketing management and basic marketing courses in business management and commerce streams can use this case.

This case study introduces students to Turkey’s economic crisis in 2021 and how the Turkish lira’s depreciation, home inflation and central bank policies interact to affect its various financial markets. In the bond market, a depreciated lira heightened the credit risk of Turkey’s bond issuers and effectively crippled the country’s bond market. In contrast, Turkey’s stock and cryptocurrency markets experienced a rally as Turks put their money into equities and cryptocurrencies to hedge against inflation. In international trade, the lira’s fall and the supply chain disruptions in Asia benefited Turkish exporters tremendously. In contrast, Turkish importers suffered. In the Turkish society, the impact of the currency and inflation crisis fell the hardest on ordinary folks, who saw the values of their wages and pension benefits erode.
