Hi again,
I'd like to suggest that every employee should have their corresponding Nations listed next to them. I've noticed that a Nation's happiness in this game depends on the Nationality of your employees (for example, I have 4 Soldiers from the Commonwealth of Oceania, 8 scientists from The Middle Eastern Alliance, and I receive funding from these Nations based on how many Soldiers are from the Nation + How happy the Nation is.). By doing this, you can vary your team of Soldiers, Scientists e.t.c so that you keep each Nation relatively content by picking Employees from each Nation.
Sorry if I've confused anyone.. lol
