Wipro — In regards to my appraisal

Address:

Hyderabad, Andhra Pradesh, 500081

This is in regards to my appraisal for this year. I want to discuss about the comments that i have received. I have worked very hard and this is really disheartening to receive these kind of comments. When i have asked manager on what basis they have given this appraisal they said we have to randomly select a person to give a low rating.
I have already discussed with my tl, manager and h. R. And non of them have any explanation. They said we cannot provided everyone with good rating and said its not that your performance is bad, its just that we have to select a person randomlly. Last year i have recieved more than 33% hike and this year. Its zero.
