After receiving complaints of unfair appraisal from staff two years ago, HDFC bank has recently completely redesigned its human resource and more specifically, appraisal processes. The controversy began when senior management received a rating of 4 and all junior staff only received a rating ranging from 2 to 3. As a response to this, HDFC now increased its management training program by 15-20% on feedback systems and providing long term performance rewards for staff. Furthermore, an online system was created to ensure managers responded to questions raised about discussions with staff before any rating or feedback is submitted. 

Bias plays a significant role in unfair appraisal, and may seem to be unavoidable. Often, managers are criticised for being either too harsh or too lenient, depending on his/her personality. As human resource management is becoming a more serious concern for businesses, all companies now strive to eliminate any bias that is created in the process. This can be done through training programs and case studies, which will train managers to deal with a variety of situations and act accordingly.
