In retrospect, I think you have to put yourself first. That means weighing up the options, considering corporate culture and how complaints will be taken, whether a criminal offence has been committed, EEO laws, employment laws and any laws specific to your industry. Think about what you might gain (no more bullying, improve the culture, taking a stand for what is right, compensation) and what you may lose - your job, reputation money.
Having gone the legal route after internal complaints were dismissed, I settled out of court with a large Australian corporate. I would do the same again. For me it was important to stand up for what was right and I had an extremely strong case.
