People are having trouble trusting each other, according to an AP-GFK poll conducted in November 2013, which found that Americans are suspicious of each other in their everyday life. Only one-third of Americans say most people can be trusted—down from half who felt that way in 1972. A record high of nearly two-thirds says “you can’t be too careful” in dealing with people in 2013. This can be carried over into the workplace, where employees want their leaders to be more trustworthy. Employees have grown tired of unexpected outcomes resulting from the lack of preparation. They want to be informed of any change management efforts before—not after the fact. Employees desire to know what is expected of them and be given the opportunity to better themselves, rather than be told they are not qualified for new roles and responsibilities. Here are four early warning signs for you to course-correct when employees are having trouble trusting their leaders. Lack courage Leaders that don’t stand up for what they believe in are difficult to respect and trust. Too many leaders waste too much of their valuable time trying to act like other leaders in the organization—rather than attempting to establish their own identity and leadership style. Employees know that if their leaders are not savvy (精明) enough to move themselves into a position of greater influence, it will make it much more difficult for them to get noticed and discovered as well. When leaders lack the courage to enable their full potential and that of others, it becomes a challenge to trust. Self-centered When a leader is only looking out for themselves and lacks any sense of commitment to the advancement of their employees—this shuts off employees quickly. Great leaders are great coaches and are always looking to help their employees grow. When leaders lack any real desire to coach or 'guide the career advancement of their employees—it becomes increasingly difficult for employees to trust them. But when leaders are too disruptive (指手画脚), their employees sense that they are in it for themselves and/or don’t trust the talent around them. Reputation issues When people begin to speak negatively about their leader, it makes it more difficult for others to trust their intentions. For example, look at what has happened to President Barack Obama since December 2009 when his approval rating was 69%. Four years later, Obama’s approval rating is at 43%. Many who have followed him for years are now having trouble trusting him. Every leader must be aware that they are constantly being evaluated and thus they can never grow self-satisfied. When they do, this begins to negatively impact their reputation and the trust employees have in their leadership. Inconsistent Behavior People are more inclined to trust those who are consistent with their behavior. Isn’t it easy to begin questioning one’s judgment when they are inconsistent? When everyone but the leader is on board with a strategy—you begin to wonder if their intentions are to support the organization’s advancement or their own. Leaders need to refresh their leadership style before they lose the trust of their employees. This is what today leaders must consider: how to lead in new ways that focus less on oneself, but more on the betterment of a healthier whole.
