Ethics is Universal, Flavor is Regional
I've worked in Africa, Europe, the middle east and yes, America. Ethics is a plumb line for moral character, ultimately individual in execution
While one may work for an organization that holds a strong ethics code, I have seen and worked with individuals that exceed or ignore that code. Situational, cultural, personal pressures sway the line.
The danger comes when we have expectations based on our own ethics code, by which our customers, clients and partners do not prescribe to. Ethics then becomes a catalyst for change.
