Thousands are set to take to the streets of Brussels today in the latest trade union-backed demonstration against austerity reforms by the Federal Government.
The national demonstration was organised by the Belgian trade unions CSC/ACV, FGTB/ABVV, and CGSLB/ACLVB. A similar action was organised earlier this year in March.
The unions are calling for better working conditions, a better pension scheme, and for Belgium to maintain the full and automatic wage indexation, among other things.
Demonstrators are expected to gather from 09:00 near Boulevard du Roi Albert II in Brussels. The demonstration is expected to start around 11:30 and end around 15:00 near Brussels-Midi station, according to the City of Brussels.
Demonstrators will walk through Boulevard du Jardin Botanique, Boulevard Bischoffsheim, Avenue des Arts, Boulevard du Régent, Avenue de la Toison d'Or, Boulevard de Waterloo, Avenue de la Porte de Hal, and Boulevard du Midi, before arriving at the Esplanade de l'Europe.
Traffic across the capital is set to be disrupted throughout most of the day, particularly near the route of the demonstration. Several sectors warned ahead of the strike that their services would face significant disruptions.
The Brussels Times will be covering the latest updates in this live blog as the national demonstration unfolds.

[12:04] - Renie calls for more investment in community work
Renie Cocquyt from the citizens' movement Hart Boven Hard feels that the Arizona Government is making the Belgian society more closed off.
"Paid work is the only work that counts for them, but unpaid care work and community work are the things that keep this society alive," she told The Brussels Times.
"The government are co-opting the word 'security' to talk about the economy and immigration, but a really secure society is one where people know that someone will care for them when they’re having issues, and where they can care for others in turn," she added.
