Walmart workers from around the world have gathered in front of Los Angeles City Hall, demanding better working conditions and the right to unionise the world's biggest retail store chain. The US retail giant has 10,000 stores in 27 countries, employing 2.2 million people. Workers in several of these countries have won union representation, but not in the US. The protest came after 70 Walmart workers staged a one-day walkout this week from stores in Los Angeles, calling it the first strike against the company in the US.
