You can make a report about your direct manager and the HR rep who happens to click on your case will go to the manager without even talking with you to see what going on. I had a manager laugh as the manager read me the email HR sent to talk to me about the issue. I was flabbergasted. I never heard back from HR. I'm not looking forward to my discussion with them when my number is called as part of the mass layoff agenda.
