The three categories of managers that stand out with regard to ethical and moral principles in business affairs are:

moral managers, amoral managers, and immoral managers.

highly$-$principled managers, managers with no principles and no ethical conscience, and managers with no strong convictions one way or the other when it comes to observing or not observing so$-$called ethical standards.

mostly ethical managers, somewhat ethical managers, and totally unethical managers.

managers who are "full$-$time believers" in high ethical standards, managers who are "part$-$time believers" $($part$-$timers behave ethically when it benefits them personally but are quite willing to act unethically when it is beneficial for them to do so$),$ and managers who are "nonbelievers" and have no ethical standards.

$$ ethically concerned managers, ethically indifferent managers, and ethically unconcerned managers.
