ask any HR person, just tell them you

want to file a harrassment case against an employee. what is the number you should call?

when you call that number, an HR person will ask you certain questions. be calm and tell her what happened. then she/he will assign a case worker for your case. this case worker will contact you and ask you what happened. take this chance to let out your anger. then she/he will ask you to put everything in writing, which will include, time, place, name of the person who assaulted you, what he did, name of the witness. email her everything so that this will be recorded in HR.

after that point, i would say, put a period on the statement and move on...
