French unionists demonstrate against unemplyoment and precariousness in Paris, France, on December 7, 2019. The most serious nationwide strike to hit France in years caused new weekend travel turmoil on December 7, with unions warning the walkouts would last well into next week. Macron was widely believed to have ridden out the challenge posed by the "yellow vests" whose weekly Saturday protests against inequality in France had shaken the government over the last year. But the yellow vests have also sought to utilise the momentum of the strike movement and are expected to hold protests across France this Saturday. Photo by Serge Tenani/Avenir Pictures/ABACAPRESS.COM
