The union says that it will offer support to any civil servant taking legal action to try and block the move.
The civil servants object to the move as they claim that they fear for their safety and are afraid of being mugged en route to their new offices.
The union too says that the route between the station and Thurn en Taxis isn't safe. The union's Jan Van Wesemael told the VRT that "The civil servants say that their safety is no longer guaranteed, while this was the case when they were taken on by the Flemish authorities.
Then can take this to an employment court and we will give them our full support if they do so".
The 2,600 Flemish civil servants should move to their new offices in a couple of years.
