Dear donyi_polo ,
I have also the same questions those you have made. Congratulation for your post.
They have many activities for the benefit of teachers,students,studies etc. etc.
1) They take,sometimes forced to pay their annual subscription form willing and from unwilling teachers.
2) They published Test Papers (Madhyamik and Higher Secondary) and sale.
3) They arrange/prepair questions papers,maps,graph-papers etc. and sale to the schools.
4) They arrange for annual summit with receiving a special subscription,
5) They have to let lodges or resorts for teacher-traveler.
6) They take shelter under a political umbrella and want to become a Leader.
7) They take different types of unauthorized leaves etc. to be a member of such association.
Are these unimportant ? So,they have no time to waste to protest such unfair means .
Thank you.
