Dear Tammy,Working in a group can be difficult at times, especially within the framework of a team. There are always going to be those difficult people that are always going to try to work individually (and who always think that their ideas are the best). You should consult with him about why he has been doing so, and why he has made all of the changes. You, if you can, should talk to your boss' boss about such problems; however, I would advise against this since he is not your direct advisor. There are some neat articles on [url]www.consultingcafe.com/articles[/url] that will hopefully help you through some trying situations. I know I've used this website to help others with, and I have used it within my own framework. It's a great website to use as a tool for individuals that are having problems within their office space, etc.Best,The Advisor.
