Parrikar, 62, has been recuperating at his private residence near here since October 14, when he was discharged from the All India Institute of Medical Sciences in New Delhi.
"We have now decided to go to people with the issue and launch a taluka (administrative division)-wise agitation," Chodankar told PTI.
The Congress will begin its agitation from Bicholim on November 30, followed by Pernem on December 1. All the talukas will be covered subsequently in due course of time, he said.
The party will hold "awareness campaigns" across the state, Chodankar said.
"We will expose this (Bharatiya Janata Party-led) government...we will highlight how Goa has suffered due to the absence of a full-time chief minister. The last cabinet meeting was also not chaired by the chief minister. Goa is in the ICU (intensive care unit)," he said.
The Congress leader said they are demanding restoration of governance in the state.
"We want a full-time chief minister who will hold regular cabinet meetings and advice Goa governor. Right now, nobody knows what is happening. Who is running the government in the chief minister's name? We don't know who is signing the documents and who is taking the decisions," he said.
It is clear from the photographs released recently by government that Parrikar is not in a position to take any decision, Chodankar claimed.
He said the Congress' agitation on this issue started long back when they observed a "century" (100 days) without the chief minister.
