If you have serious concerns about the qualifications of a job candidate who has asked you for a written recommendation,you should

A) avoid mentioning them in the letter of reference.
B) include allegations of misconduct in the reference letter.
C) elect not to write the recommendation.
D) express your concerns via social media.
E) show the reference letter to the candidate first.

It is unethical to provide a positive recommendation for a candidate you do not believe is qualified for the position. Therefore, the best choice is to elect not to write the recommendation. It would be dishonest and potentially damaging to the candidate's reputation to provide a recommendation with concerns or allegations of misconduct. On the other hand, showing the reference letter to the candidate first may jeopardize the integrity of the letter and put pressure on the writer to make changes.
