Answer:
Stonewalling
Explanation:
Stonewalling, as the term conveys, refers to creation of a defense mechanism wherein the leader instead of paying heed to shortcomings and issues of his team's under par performance, acts to the contrary and comes up with all kinds of evasive responses so as to defend his team.
Stonewalling is regarded as a mark of poor leadership since here, the leader is not focused upon identifying weak areas and addressing them. On the contrary such a leader adopts a denial approach wherein he tends to overlook and ignore the problem.
Stonewalling leaders are unable to extract the desired performance and results from their team since such leaders adopt an ignorant approach towards problems.
