In my opinion, it is fake. Practically, it is not possible that in five days, out of 23 co-workers, not a single person had touched him for any query. Secondly, if he is a proofreader, then after he finalizes any article, only then the final print on paper will be done. That means during these 5 days, no paper has been printed out.
IN MY VIEW, THIS IS TOTALLY A FAKE AND MISLEADING ARTICLE.
