1. Behaviors that undermine trust: A lack of consistency: Where this may be a less thought of behavior that undermines trust but plays into Shorey & Chaffins article that breaks down attachment issues. The relationship that is fostered between a leader and their followers naturally establishes an attachment style, where secure attachment is ideal. A lack of consistency in leadership treatment and behavior is likely to foster insecure attachment in some form. To further this notion, leaders and followers are people who potentially have flaws. It is possible that people bring their attachment style from childhood into the workplace. Some form of positive consistency (in prosocial behavior and treatment) may in the least help to establish the basis for a more secure attachment style between leadership and their followers.
2.Some leadership behaviors that undermine trust include narcissistic/self-absorbed, uncontrolled unconscious/implicit bias and microaggression. In Northouses Leadership: Theory and Practice, he speaks to the Toxic Triangle and under the Destructive Leaders piece, he mentions narcissism. Narcistic leaders when placed or leading in an organizational environment that allows that behavior to continue instead of cease places that leaders subordinates in a climate of destructive leadership and will quickly dissolve any level of trust the subordinates had with this leader early on in this leadership climate. Reasons why leaders that described as narcissists (by multiple people as opposed to just one) according to Northouse is possibly due to that leader possibly traumatic background, self-hatred, etc. Artika Tyner mentions the impact of implicit bias and microaggressions in the workplace and by leaders. Implicit bias if uncontrolled and not kept in check will also lead to a negative and eventual toxic work environment, coupled with the effects of microaggressions (which have no place in the workplace, let alone by leadership).
