Thousands of Belgian postal workers marched through the capital Brussels on Monday at the start of a three-day strike.They were protesting about their working conditions, privatisation, post office closures and future job losses with the replacement of full time staff by temporary workers on lower wages. The Belgian unions also complained the state owned Danish Post is selling its almost 25 percent stake in the Belgium Post Office to private equity firm CVC Partners. The sale has earned the Danes a profit of more than 200 million euros in just three years. The postal unions said over two thirds of the 37,000 workers walked out. Management insisted more than half of Belgium’s mail was delivered on the first day of the strike and that 80 percent of post offices were open though many with just one counter operating.
