Thanks for the response. "Normal" is a very subjective word, isn't it. I think that is what we struggle with today...vastly different ideas about it.
As an AD or principal, I would be OK with a HC telling me that "texting is fine." The problem I see is that there is sometimes little accountability when boundaries get crossed/rules get broken. The "I don't have time to monitor what my people are doing" card gets thrown. Have experienced it first hand, sir.
When somebody who works for me says "no problem," I give them plenty of rope...to operate freely or hang themselves. I am responsible for my reports and ultimately accountable for their behavior, which reflects on me and could ultimately cost me my job. For that reason, I have every right and responsibility to question their texting behavior, especially when there are multiple examples out there of coaches using this technology inappropriately.
It is ridiculous we should even have to have this discussion, right? Unfortunately, adults often don't act like adults, forcing the issue.
