Dear [recipient's name]:

I am writing to seek your assistance in resolving a matter with Joe Robbins in our department. As you know, Joe and I work closely together on numerous projects. However, some situations have occurred recently that I have been unable to resolve on my own. Joe has interacted with me in a highly offensive and unprofessional way and has not adequately contributed to the work involved in our projects. Thus, I have had to work extra hours to complete the work that Joe did not complete.

Please contact me so we can discuss this further and determine how best to resolve this situation. Thanks in advance for your time and your attention to this important issue.

Sincerely,
