What if you get a D band and minus 20% hike because you are not coming to office. What will you do?

This is not a valid point. If you are not compliant with RTO but you are good performer then there is no way to get band D. Either you are low performer or not performing at all or you are on bench then only you will get D

My rto is also 0 . If I face this situation. I work even hard to switch job ASAP

Minus hike? Is it possible ?
