I thought I would post a question that has bothered me for sometime at my new club. I am the Head pro at a rather large 8 Indoor court facility. The club has myself and 2 staff Pros as well as several Independent Contractor Pros to help with various activities and and Lessons. There has been an ongoing "problem" in our Open Junior Drill sessions where The Pro conducting the Session takes it upon him/herself to attempt to make technical corrections to students he/she knows are currently taking private lessons or Training with another Pro. Technical corrections refers to grips, stances, swing paths, and other technique issues. My personal belief and what I have been taught at other clubs is that it is not acceptable to make these types of corrections to a student you are not in a student/teacher relationship with on a regular basis. They are paying someone else to make these corrections, they came to the drill sessions to do exactly that--do drills and hit balls. This is what I consider professional courtesy to your fellow Pros. My personal problem is that I primarily work with tournament players and players who want to advance into competitive tennis. The Pros who conduct the sessions really donot possess the technical knowledge to understand or teach as Dave Smith would say--an Advanced Foundation. Or Modern Tennis--open stances, semi and full western grips, angles, swinging volley,correct footwork and movement etc... My second Dilemma is that I have several kids in some of my programs who also take some other Pros and have some stroke deficiencies which if not addressed would prevent them from reaching their goals-but I leave it up to the student to take it up with their personal Pro to make these corrections and then the student and parent to make a decision about what is best for the player in the end. So where does one's responsibility end with the players on the court?
