The World Health Organization (WHO) has warned that the Omicron coronavirus variant poses a high risk of infection surges around the globe. The head of the organisation, Dr Tedros Adhanom Ghebreyesus, renewed a call for a global push to get vaccines to poorer nations meanwhile in the US, workers in one of Amazon's warehouses in Alabama have been allowed to rerun a vote on whether they can join a union. Employees voted not to form a union in April, but the National Labor Relations Board found Amazon illegally interfered in the elections. Rebecca Rainey, Labour and Immigration Reporter for Politico, explains. Plus, Twitter co-founder Jack Dorsey is stepping down as chief executive of the company. Mr Dorsey, who co-founded Twitter in 2006, will be replaced by the current chief technical officer, Parag Agrawal. We ask the Financial Times correspondent Dave Lee why Mr Dorsey has given up the top job. Later in the programme, an episode of the cartoon The Simpsons, which refers to Tiananmen Square, does not appear on the Disney+ video streaming platform in Hong Kong. The omission of the episode by Disney has added to growing concerns about censorship and self-censorship in Hong Kong. And we talk to Karen Chan, a neon light designer in Hong Kong, about the movement to revive the use of neon in art, commercial spaces and signage.

We're joined throughout the programme by Rachel Cartland, an author, writer and expert on Hong Kong and Peter Morici, an economist at the University of Maryland in Washington.
