As a leader, people are going to lie to you occasionally. Even if it is simple lies of omission.

Here is a video from Dr. Romie about some signs that someone might be lying to you:

This is a good video, probably worth watching, but let me summarize it for you. How do you know when someone is lying?

1. Use of negatives - A person who is lying about calling you back might say, "My phone is so stupid!", "I hate my cell phone provider!"
2. Use of complex stories and run-on sentences - A person who is lying will tend to provide a more complex explanation, "I had a flat tire and then my boss called and then I ran into an old friend and couldn't get away."
3. Use of third person - A lying person may avoid talking about themselves and their emotions.

I think as a leader you have to be aware that people are going to lie to you and hide the truth from you sometimes. There can be a lot of different reasons for this.

The big question for you is: what are you going to do about it?
