understanding issues

They talked about being a ethical person and being fair. They said that if you are not a ethical person you are not going to be successful person in life. So if you said that you were going to do the project and someone else did almost all the work for you. You have to stand up and say  she/he did all of the work. I hope that your teacher/manger will understand. So never take credit from somebody else work. Or else you will not learn anything.
