Dear Ravi,
Absolutely, communicate and make your case to your manager and HR, but also listen to and learn from what they have to say - rather than trying to convince them to change their minds. There are so many things that you can "proactively" do during project down time - helping others, skills improvement, management assisgnments, etc. And, there is nothing wrong with asking your manager for ideas and work. So, make sure you come to work on time, perform your assigned duties to the best of your abilities, seek out additional ways to contribute, and periodically communicate with your manager about your performance and potential assessment or grade so that come review time, you are assessed accurately and fairly. There really should be no surprises to either party during a perfromance review. Chalk it up to experience, learn by it, and let it pass.
