For many successful, large organizations, growth of the company means the expansion of a wider range of employee backgrounds. With many diverse backgrounds, cultural and behavioral differences may cause confusion and frustration in the workplace.
One thing to remember about sexual harassment: it is about power, not sex. Victims are usually highly avoidant and unwilling to report such instances, which is why a large percentage of sexual harassment claims go unreported. In situations where you have a serial harasser, such claims may not come out of the woodwork until years after one employee or former employee comes forward. Clients and customers can be harassers as well.
