The mobilization was called by the General Federation of Belgian Labor (ABVV/FGTB) as part of the national day of action for more purchasing power and against inequality.
This protest is a part of the series of demonstrations that have been taking place in Belgium and across Europe demanding action on climate change.
Three major trade unions representing around 4 million workers staged a strike on February 13. The workers alleged that the government had put a cap on wage hikes, leading to them losing out on benefits
The call for the protest was given by two students who were inspired by 15-year-old climate activist Greta Turnberg from Sweden, who addressed the climate summit in Katowice in Poland.
In many places, the protesters marched wearing yellow vests in solidarity with the French protesters (of the Gilet Jaunes or the Yellow Vests movement).
