How teachers get involvement in teaching and activities? Care to know? After the dragon boat incident!

How teachers get involve? How do teachers started the career as a teacher?
This will lead to how one of the young brave teacher's fate was determined when he chose to be a teacher.
First, any young teachers will be asked to teach any subjects that the stable seniors don't teach any more.  This is due to the fact that the senior are more reliable in their teaching which are quite true after years of experience. In addition they are not moving (transfer)any where else as they have families or even if not, used to the condition of the schools.  Most people don't like changes especially when the age is catching up. 
Next, the younger ones will be given activities that again the smart senior teachers take their hands off as they realized the danger and the hard work needed to pour in. It's sounds quite reasonable as their age do not permit them to run around like the youngster any more.
So, that's how the dragon boat became the younger teacher's responsibility.  And so on with the other adventurous activities.
As young teachers, you have no say in what you wish or not wish to do.  You just leave your fate to whatever that arrange nicely for you just because you are young.  Young is consider innocent, braver, will do all out and do not realize the danger in return.  Of course, there were some clever ones who rejected but will be penalized in terms of some other way, some how.
As years passed by, a young teacher will became wiser in whatever activities involved. They will then be the senior teachers and will be stable and given trust in works that are suitable and might be according to what they wish at last.
This type of tragedy will usually involved the younger ones, sorry to say that.  Some might not agree, but in most situations in schools, that is what is really happening!  Don't believe, become a teacher!
Teachers are expected to be all rounder and are expected to be able to handle any situation in both teaching and activities.  I was young once and went through the same fate.  Just lucky nothing happen to all of us and we really had a great time as the teachers are just as innocent as the students.
The procedures and precautions don't really play an important role as some students tends to keep it away from their parents by signing on behalf.  No parents would allow their loving children to involve in dangerous activities.  It might work for the girls but not the boys.  The only way is to phone to each and every parent whom their child are involved, just a suggestion.
What can we say and how do we know?  Guess is not a question for any one of us to answer.  It's God's will and we have not much choice just like the young teacher's fate in their given work and responsibilities.  But one thing we are sure to know, is that the young teacher is just like any other young teachers who dare to take up whatever given and work all out for it even if he do not know how to do it.  He is just there to take care the students and to carry out the duty being asked to do so without rejection! 
I wonder if the insurance for young teachers will increase if they realize that actually the teachers' work is just as risky when you are going out for activities with group of students!  Only when you are young!
