Prof. Steve Knight (INSEAD), says that genuine authenticity is not restricted only to when you are in conversation with your boss or your clients, or aiming to secure that lucrative contract, or being interviewed for your dream job, or when you are presenting at a conference, or participating in a meeting. It is not a tap on, tap off quality. If you are 100% genuinely authentic and you truly know who you are, the context of where you are and who you are talking to should not change the core of who you are and what you stand for. It should not therfore fundamentally change the way you communicate. You will certainly adopt different tactics in your style of communication, i.e. formal or informal and indeed what you might choose to wear, but it should not change the essence of who you are.
