The most influential people have a balance of perceived power and likability. We want to believe that you are credible and can make decisions that might make other people angry. We also want to like you and trust that you have good will towards us. Both characteristics help us influence others, and most of us tend to favor one characteristic over.
You seem to be well-liked by your co-workers. People see you as warm because you are expressive – you show more positive emotions than negative. You like harmony and often choose to keep the peace over taking a stand. Because you are liked, you are probably included in most social functions and may even be asked to arrange the entertainment (or BE the entertainment!). Co-workers trust you and confide in you because you have excellent rapport with most everyone.
The downside is that people may not take your ideas seriously because you are perceived as less powerful. You may be too reluctant to disagree or make anyone feel uncomfortable by “coming on too strong.” You tend to be a peace-maker and value harmony. If your perceived power level is very low, people may not trust that you will stand up for them (or yourself) when conflict arises. When push comes to shove, your team may choose someone else to represent them who they feel can withstand the heat better.
Raise your perceived power levels to become more persuasive and be taken more seriously at work.
