When working with others, always do your best to be professional, respectful and courteous. Provide them respect, attention and dignity. No matter where they may work, above it all, they are people, just like you and your leadership role makes you even more accountable to ensure fair treatment of all employees.
This extends across everyone you meet and work with and should you experience concerns that need to be addressed, always do so privately, one on one, behind closed doors. Remember, praise publicly, correct privately.
