In the real world, if the person who is doing the bullying is more valuable to the organisation than their victim then the victim will be burned.
The classic case is the high flying executive who sexually harasses an a young women from the typing pool. They just sack the person from the typing pool and let her know they have really deep pockets to fight any tribunal they might dare bring.
If the bully is more important than you, look for another job
Sorry but that is the way of the world
