Brussels airport – Belgium`s largest - cancelled all departures as security workers downed their tools. Charleroi Airport, a major European hub for low-cost airline Ryanair, said it could not operate any flights due to lack of staff, writes France24.

The strike is the last in a series to hit the European country since Flemish nationalist Bart De Wever took office as prime minister in February.
Grappling with a budget deficit whose size violates European Union rules, the government is looking to reform pensions and make other savings that have infuriated trade unions.
"This government promised more sustainable jobs and increased purchasing power. Hot air! And once again, everyone is paying, except the rich", trade union CSC said, calling on people to take to the streets in protest.
Unions expect tens of thousands to join a rally in Brussels on Wednesday, as delays and cancellations also hit the capital`s metro, tram, and bus services. Police in the capital advised citizens to avoid some central areas and travel by car".
