A lie is saying something that's not true. It's not suppressing the a compulsion to act like a total jackass, no matter how much you really want to. If my boss asked me for an opinion on something I thought was a bad idea, I'd express my thoughts (with empathy). Honesty is not immediately blurting out every thought that passes through your mind, and it's not dishonest to withhold information that people aren't entitled to. You're (perhaps intentionally) confusing honesty with openness. Sometimes it takes courage to be honest, but in my opinion, there's more dangers in dishonesty.
