All flights to and from Brussels airport were cancelled from 6am on Friday after firefighters and security personnel began wildcat action due to a dispute over overtime.
The pickets were set up at 6am and the strike lasted for a total of 11 hours, Brussels airport is not releasing details on the number of flights and passengers delayed but the numbers will be high and there will be a knock-on effect over the busy easter weekend.
Strikers were angry over the day to day behaviour of management and were demanding better relations with management. Their main demand was for their overtime hours to be paid in full.
