Chettinad Vidyashram — Not obeying government orders

Address:

Chennai, Tamil Nadu, 600026

Respected sir,
My son is studying in chettinad vidyashram (Ra puram, chennai-26) std12. As per the government order, all schools of the state should reopen only on june 7. But when we called the school today, they are saying that for std 12, school reopens on june 1st and students should wear colour dress and the timings are from 8 am - 2:30 pm. The students would suffer a lot because of high temperatures. What is the use of government orders?. The government clearly mentioned schools of all sections.
Please take the necessary actions.
With regards.
