Although the concept may be a little obscured by technology, social media, and our near chaotic environments (amongst other factors), at the core of all human relationships, and therefore business relationships, is the concept of integrity.
Nobody can consistently fake possessing integrity for long. We can forgive incompetence, ignorance, bad manners, and even being plain wrong from time to time. But a person with dubious integrity, and therefore a poor reputation, is despised and to be avoided. Tolerating a person with questionable integrity in a management position is like poking a hole in the organisational canoe.
What are you doing to encourage and maintain integrity in your organisation?
