Most leaders today are aware of the need to look confident, powerful, and assertive, but fewer understand the impact of empathy and warmth. And this may be more of a career-limiting factor than they know.

As organizations move toward more collaborative cultures, your success as a leader increasing depends on your ability to make team members feel valued, respected, and included.

While power and confidence are non-verbally displayed by expanding into height and space, when you want to encourage collaboration, you’d be wise to replace those status cues with warmer ones – and that starts by keeping your body relaxed and open. Not doing so is a body language mistake that can sabotage your leadership effectiveness.

Here are six tips to keep in mind:

1. Relax.

In open and receptive postures, legs are uncrossed, and arms are held away from your body, with palms exposed or resting comfortably on the desk or conference table. Studies show that leaders with open body language are perceived more positively and are more persuasive.

2. Lean in.

Leaning is another way your body makes a statement. Leaning backward usually signals feelings of dislike or negativity, as we subconsciously try to distance ourselves from anyone we don’t like or trust. On the other hand, liking and trust is often displayed by leaning forward – especially when sitting down. But if you are using forward leans as a means to build positive relationships, be aware that early leans can make people uncomfortable and decrease their perception of you as likeable. So wait until you’ve developed a level of interpersonal comfort. Then make your move.

3. Align your body.

When it comes to the body language of inclusion, facing people directly when they’re talking is crucial. Face the speaker with feet, hips, shoulders and head aligned in his/her direction. Even a quarter turn away signals your lack of interest and makes the speaker shut down.

4. Mirror.

Mirroring is another nonverbal sign of empathy and inclusion. You may not realize it, but when you are dealing with people you genuinely like or agree with, you’ll begin to match their stance, arm positions and facial expressions. It’s a way of signaling that you are connected and engaged.

5. Use your head.

The next time you are in a conversation where you’re trying to encourage someone to continue speaking, try nodding your head using clusters of three nods. Research shows that people will talk three to four times more than usual when the listener nods in this manner.

Head tilting is another signal that you are interested and involved. So head tilts can be very positive cues when you want to send messages of empathy and understanding. But a tilted head may also be subconsciously processed as a submission signal. (Dogs will tilt to show their necks in deference to a more dominant animal.) So don’t overuse this signal.

6. Look like you’re paying attention.

Of course, paying attention when someone else is speaking is one of the warmest signals you can send. So at your next meeting, avoid the temptation to check your text messages, check your watch, or check out how the other participants are reacting. Instead, focus on whoever is speaking to make sure that he or she feels valued, respected, and included.
