I'm generally inclined to agree with that sentiment. But I do have a much stronger reaction to a lie when it directly undermines trust I have placed in somebody. If a colleague or employee tells me a lie about their personal life, I'm not going to feel as strongly about it as if they were to lie to me about something related to work. I don't trust my colleagues to tell me detailed and accurate information about their personal life, but I do trust them to do their work with honesty and integrity. Although any lie is still going to undermine trust in general to some extent.
