Both of our children are athletes (basketball) and we travel to tournaments all over and they play with their school teams as well. While Sherry has her own position on teams this is how our family feels about it...
Our kids have always been taught that "team" is really a singular noun. There is nothing plural about it. A team is viewed as one and that's how it operates. You win as a team, you lose as a team, you behave or get into trouble as a team. The actions of a few sometimes affect the many and that's why we've taught our kids to be leaders in their teams. By a leader they know how important peer pressure is and they've been taught that every team needs a peer leader to help the team as a whole make the right decisions.
This is not to say that we have two bosses. They simply lead by example because they know that when they are part of a team, someone else could do something stupid (such as this case) and affect them. Every decision our kids make is made knowing that they will affect their teammates...right down to something like grades. If they aren't eligible to play because of grades, the entire team suffers the loss of a player they need, etc.
We have also coached and chaperoned about a million trips from athletics to field trips and we take it seriously. We even typically get the "problem kids" whose parents are never involved because we don't play around and they will "tow the line" when they are in our group.
To believe the team mentality when it works in your favor and then change your mind when the true meaning of team is tested is not doing yourself, your child, or the team any favors. Saying your child is part of the team but shouldn't be punished with the team causes a rift in the team which will affect game play, attitudes, etc.
Just my thoughts on things. Moving on now.
Very nice. One thing I would like to add from my own experience being on teams. I was not very athletice yet I was on sports teams. I was on academic and extra curricular teams (math team, choir and band). In my many years working, I have been on teams to develop procedures and projects, the most important thing that I have learned from being on a team is that you learn to stop thinking about yourself, and think about how your actions will affect others.
It is not "will I keep my 4.0", but how can I help our team get the best score. It isn't "will I get in trouble" but "did I bring the team down and disappoint them". It isn't easy to be on a team, because you have to think about others and how your part fits in with them, but when it works it is a good thing.
