A practical guide specializing in business communication training to improve subordinates' management skills. - Title: B Course: Managing Subordinates - Author: Isoroute - Contents: Training content related to business communication - Chapter: The Mindset of a Supervisor I took this course when I was attending a business school for communication. It's a thin booklet of about 80 pages, but the content is quite substantial and I found it very educational. It has been stored at home for a long time, so there are scratches and folds on the cover, but the inside is clean.
