His entry into politics was after his rigorous engagement in organising teachers’ unions in the state.[3] He was earlier a teacher at KTM High School, Mannarghat and later became the Head Master of the school. He was part of the Kerala State Education Advisory Board and a member of the Syndicate of Calicut University. In his long career in the teachers front of communist party, he was first elected as the Malabar Regional President of Kerala Private Teachers Federation and later the General Secretary of Kerala Private Teachers' Union (KPTU).
