A protest outside Taiwan's Parliament descended into chaos yesterday as workers angry over a proposed cut to public holidays attacked a lawmaker and threw smoke bombs. Senior Democratic Progressive Party official Ker Chien-ming was shoved, punched and splashed with water as he left the Parliament building. The controversial amendment to the labour law has sparked a number of rallies and a hunger strike, with protesters accusing President Tsai Ing-wen of betraying her campaign promises to protect labour rights. Workers would be guaranteed one mandatory day off a week under the revised law, in keeping with current rules. They would also be given an additional "rest day" and paid at a higher rate if they are asked to work on that day. But seven annual holidays would be scrapped.
