don't blame each other..
Our aim & work is only teaching.. Mai sirf yeh eh kehna hai ke , teachers nu sirf teaching da kam he dena chaheda hai, na ke other works (Daak , Pay bill, funds & maintenance of record etc) , it effects our teaching work.. So put this demand to Govt that "no nonteaching work for all teachers"...
Dont fight with each other, every one is master in his work or subject.
I also want to mention that weakness , mastery , knowledge & expertness all of these depends upon person to person..
