Plagiarism is when someone has written something and someone else takes credit for it. Doing this is as if you are stilling from someone. It is not right even copying someones work is also plagiarism. If you are at a work site and your co worker has discovered something it is not right for you to run and tell the boss as if you have discovered it give the credit to the person who actually found it. THINK if it was you would you want them to do you like that?
