The city of Reykjavik has a policy for handling complainers – fire them. During the time I worked for the city, there were three cases where people complained about bullying in the workplace. All of the complainers (aka “victims”) were fired, but all of the bullies still work there. I myself complained about illegal working conditions, and I also got fired (the working conditions are still illegal). It may not improve the situation, but at least they can say that they don’t get many complaints.
