I don't think that lot of burden to the government school teachers becasue of elections. As what other thing they do in the schools? If you go to any government school in the rural area, you will get the know about the government teachers. They are getting good pay and don't want to work. they come to school whenever they want and go whenever they thing that its enough time to spend in the school. so lets move to home.
So in my thoughts, its not much burden tot them. i agree that yes as compare to their work in the school. its lot of burden as they don't do anything in school.
