There are some really good pointers here.  I love the old saying "if you think that you have a problem, you probably do."  The question is usually....who should become involved and at what level ?  Don't you just love it when you ask someone to straighten things out and the problem just become worse ?  Misunderstandings eventually cause hurt feelings.  Often, these things can be avoided by over communicating up front.  It takes a little more time, but can stop conflict from ever happening.  Good article !
