The personal barriers are as follows:
1. Lack of proper incentives: When there is no motivation or incentive for communication, subordinates may not take initiative to communicate.
2. Unwillingness to communicate: Sometimes, the subordinates are not willing to communicate with their superiors because they believe that if information is not correct, it will adversely affect them.
3. Lack of confidence of superior on his subordinates: Communication process is hampered when superiors do not have faith or confidence on the competencies of their subordinates. In such cases, superior may not seek advice or opinion of the subordinates.
4. Fear of challenge to authority: A superior always aims to maintain a higher position and prestige in the organisation. If he fears that a particular communication may adversely affect his authority, then he may withhold such communication.
