"It (the decision) comes as a big shock that Pongal festival, which was a compulsory holiday for the central government employees in Tamil Nadu, has been made restricted holiday," she said in a statement.
Pongal is a cultural festival being celebrated for long transcending caste and religious feelings and it is the Centre's "duty" to provide a holiday for the families to celebrate it, she said.
"The Centre should realise and accept the rights and feelings of Tamils and give compulsory holiday for Pongal," she said.
Sasikala said due to the efforts of late Chief Minister Jayalalithaa many rights of Tamils were upheld and the state is now waiting for the Centre to meet its expectations and ensure its rights in this matter, she added.
