Ask HN: Anyone had a manager with a sales background run a technical department?

My company has just taken a nose dive due to employing a sales manager as the new COO, and he fails to understand that the technical department is what keeps the company running and without us the company would fall over. His focus is on the sales department and he is making massive changes to our shift pattern without understanding why it is the way it currently is, it basically equals 30% more hours being worked for no extra money. This is to allow more staff in during the day to develop new products to be sold.

Anyone else suffer at the hands of a COO that appears incapable of understanding the technical side of a business?
