The Confederation of Trade Unions is calling on workers and their bosses to join a citywide strike on Monday to protest against the extradition bill. The pro-democracy group advises workers to write to their employers notifying them of their planned action. It says bosses, meanwhile, should let their staff take the day off to join a rally organised by the Civil Human Rights Front. Annemarie Evans asked the CTU's chairwoman, Carol Ng, about a sample letter they're offering workers who wish to take part in Monday's action.

Hong Kong people are being asked to consider how they can help rein in climate change - by reducing the city's carbon emissions. The Council for Sustainable Development has launched a three-month consultation on Hong Kong's long-term de-carbonisation strategy, to try to help limit the rise in the global temperature to within 1.5 degrees by the end of the century, as per the 2015 Paris Agreement. That's going to require some sacrifices in people's lifestyles and habits. Council chairman Arthur Li said the panel will hold forums and issue an online questionnaire, before compiling a report to the government at the end of the year. Jim Gould asked Albert Lai, the CEO of the advisory group, Carbon Care Asia, what his advice would be on how to reduce carbon emissions.

Women in Switzerland staged a nationwide strike on Friday to protest what they say is continued sexual discrimination. The main protest took place outside parliament in the capital, Bern. The protest came 28 years after similar action saw 500,000 women take to the streets in 1991. Swiss women have long campaigned to accelerate the pace of gender equality. They joined millions of other women in Europe after World War One ended in 1918 in demanding the right to vote - but did not get it until 1971. At the time of the 1991 strike, there were no women in the Swiss government, and there was no statutory maternity leave. Annemarie Evans told RTHK's London correspondent Gavin Grey she was startled by just how backwards Switzerland still is.
