They only want hike in school fees.. As if they will increase salaries for teaches..even if they do it it hardly makes a difference. And moreover if a teacher resigns with completing the contract even for a genuine reason with regards to health the school does not pay the end of service benefits no matter since how many years you have slogged in that school and above that you have to even pay back some fine to them. Management of schools are least concerned about all this. All matter is their bloody profit.
May be the teacher if she dies due to health issue only then they might react.
