Hello there!
Your question asks which is NOT a critical step to improving business ethics.
Answer: Minimizing penalties for violations
The reason why the answer choice "Minimizing penalties for violations" is the correct answer because this is something that doesn't help improve business ethics.
If you minimize the penalties for violations in a business space, how is that improving work ethic? You would be allowing people to do things that would hurt the business, but then penalize them lightly. That's not improving the business ethic, it's only going to make the business ethics worse. Minimizing the penalties is allowing people to perform violations that you don't want to see in a business. If they were to increase the penalties for violations, that would be another story.
Why the other answer choices are incorrect:
Answer choice "management training" is incorrect because this is one of the things to improve business ethics. If you get your management team to go to trainings, then they'll be ready for more things as management.
Answer choice "enforcing the policies" is incorrect because this is another thing that improves business ethics. When you enforce the policies, you're making it clear to everyone that they have to follow those policies, or unless they want to get fired.
Answer choice "management support" is also incorrect because this is another thing to improve business ethics. In a business, the management is on top of everyone, and they need great leadership skills in order to make the business succeed. if the management is getting support, then they'll be able to complete tasks in a orderly manner.
I hope this helps!
