Raju had resigned early last month over the decision to bifurcate Andhra Pradesh and has kept away from his Ministry and official functions. His resignation has not been accepted by the Prime Minister.
The Minister had skipped the crucial Central Advisory Board of Education (CABE) meet here on October 10, entrusting his officials to chair important engagements.
Today, however, he turned up at a workshop on 'designs' here along with Higher Education Secretary Ashok Thakur and advisor to the PM Sam Pitroda, saying he was only addressing those seminars that "I feel are productive to me".
"I am going through a very different way of working myself. In reality I have quit being a minister, I have submitted my resignation to the Prime Minister which he has not accepted as yet, its been over a month.

"So I have found a new way of working. I work out of home now, have flexible timings," he told the gathering with a broad grin on his face.
"I address the seminars that I feel are productive to me. So I have that luxury of having resigned and not yet out of the job," he said.
Sources said he is also expected to attend a meeting of the directors of National Institute of Technology (NITs) here tomorrow which would be chaired by President Pranab Mukherjee.
