Yes. Normally there is a point of contact in a department if you make a harassment complaint. Oftentimes the point of contact rests with HR. Sometimes it's with labour relations, and sometimes elsewhere in HR, but it's a dedicated person.
When somebody files a complaint or comes forward and wants to hear or understand how to proceed and whatnot, you need to have someone to explain to you what's going to happen in a formal or informal process. You need the same thing to support the respondent. Just because you are facing a complaint does not mean you are guilty. This person is also affected. He or she also needs some kind of support to understand how the process will unfold.
