Exactly this. In such situations the culture of abuse is deeply embedded in the organisation, so everyone from senior management through HR down to junior staff will turn on you; they'll make your work environment unbearable, berate you for any compassionate leave you're granted (assuming you can squeeze that much out of them), hold 'investigations' that exhonerate the company and the accused even in the face of blatant video evidence, downgrade your performance appraisals, and, since senior staff tend to have friends at other companies in your industry, potentially make it difficult for you to get a job elsewhere. Anyone who comes forward in such circumstances (having, let's not forget, already suffered bad treatment through no fault of their own) demonstrates a great deal of bravery.
