This question already has an answer here:
I know there are a lot of discussions about this topic in this forum and I read all of them but my situation is slightly different. I took a class with my professor and I worked in his research lab and I know him for a while. When I asked him for a letter of recommendation he told me send you CV plus draft of your letter of recommendation. In this forum a lot of people said do not do that it is unethical. I understand this and I understand why it is unethical but what should I say to him should I say this is unethical and I cannot do that or should I forget about letter of recommendation from someone who I worked in his lab.
