Interesting .... I once had a boss that may have been cut from the same mold, however, he did not open up to anyone, was harsh not only with his subordinates, but also with the customers.  I think he expected everyone to have the same rigid outlook on life, and anyone that did not agree (again including customers), wasn't worth his time or effort.

His leadership style and closed face way of dealing with everyone was eventually his downfall, and almost the downfall of the company!  Fortunately enough customers (and workers) had voiced their concerns to upper management, who tried hard to work with the guy, before irreparable damage was done.

He was let go.  His manner was such that even with his dismissal, he blamed the company, workers and customers for his dismissal - citing customers wont listen to reason and the staff don't take direction when given.

Rather a sad end to his career in management, as I think he may have been a terrific leader underneath if he had just been able to get outside his staunch belief of his overpowering strength and always being "right" in all situations.

Eventually I was promoted to his position and had the value of learning from his mistakes to ensure I and my team were ultimately very successful.

Thank you for a great article that should help some great leaders really understand the value they can get from just opening up and working with their people.
