Giving Feedback to Your Boss

One of the issues we've heard repeatedly in this project is the challenges staff and contract SANEs feel in communicating with their managers and agency administrators. Not feeling like they have a voice and not feeling like their concerns are being addressed has led to problems with retaining good quality, competent nurses. So I was pretty interested in this article over at the Harvard Business Report's Best Practices blog, How to Give Your Boss Feedback. I have to tell you, I found a lot of the advice to be pretty reasonable and applicable to our work, as well.
 
I'll be interested to know what you think and if you have any other strategies that seem to work.
