If the company has been dealing with you unlawfully you need to document everything for your own records. Every company now monitors what happens on their computers, so you should use a paper notebook or a personal device that is not connected to the company network. As soon as reasonably possible after it happens you need to document the time, place, who did it, who was around, what happened. If you can remember past events you should sit down asap and document those. After that read the company employee handbook to check their official policies on those types of events. This is important for understanding your rights and future options. Some companies don't have their own policies but they are required to follow certain laws, depending on the country. Then talk to a reliable lawyer who specializes in these kind of suits, you don't need to retain them yet, but talk about your options. You can go with a parent or friend for support. Next, go to HR to explain what happened, show them a PHOTOCOPY (always have multiple copies for your own record, never trust some one else with the only copy) of your evidence, and inform you expect them to handle it quickly, DON'T SIGN ANYTHING take it to a lawyer or take it home if you don't understand it. Tell them you have a lawyer and are prepared to take legal action if they don't act. If they give you attitude or won't do anything you HAVE to follow through and retain a lawyer and sue them or file to start some kind of investigation. If you don't the problem will continue or get worse. You should also consider contacting several newspapers and any government officials who investigate these incidents, you can do this anonymously if you prefer. The bad news is that your job will likely be worse while this is going on or you might be fired.
