Can you stop a bus by yourself? Have you ever found yourself "underneath the bus"? Maybe in a management meeting and you get "bus driven" by a colleague that has decided that it was in their best interest to take a "pot shot" at you to make themselves look good, demonstrate fear or infer incompetence? The good news is, you're not alone. It happens every day. In most cases, it is simply a sign of immaturity or insecurity.
Fortunately, it usually reflects negatively on the person who intends the harm but that doesn't take away the sting! As a preventative step, I would suggest managers discuss topics like this regularly and openly with team members. Establishing "trust and rapport" with staff will all but eliminate this from happening. Open dialogue creates comfortable work environments and helps staff to understand that there is a time and place for everything.
Save yourself from any unnecessary frustration by focusing on the LLTR Principles: Like, Learn, Trust & Respect. Ask yourself,..."Do my staff and peers like me at some level?", "Can my staff or peers learn from me?", "Do my staff and peers trust me?" and "Have I earned the respect of my staff & peers?". If you feel confident in the LLTR principle, the only "bus" you'll need to be concerned about is the one you catch at the street corner.
