Is your issue with parents not staying the **** out in general or more so HOW they approach their concerns?
I tend to not have any issues with it personally, not recently.
The issues that seem to be the ones that cause problems are more about not staying the **** out.
How they approach, I don't have an issue if they are upset or angry. I totally understand that "Mama Bear" concept, so I tend to treat that with grace. Parents can often times be very mad at their kid, worn out, tired and have tried everything...and sometimes that frustration spills over in an "angry" email or phone call. I get that, it happens.
Now, when it came to coaching, I had a 24 hour rule. No contacting me or my staff until 24 hours after the game. Tended to give parents a chance to cool off.
Of course that did not mean they could not contact us about injuries.
