Mr Komsan said this was one of five resolutions made at a meeting between representatives of state enterprise labour unions and the People's Democratic Reform Committee (PDRC) secretary-general Suthep Thaugsuban at the Government House's Santi Maitree building on Sunday.
The meeting was intended to lay down an operational plan to retake sovereign power.
The five resolutions reached at the meeting are for all state enterprise labour unions and their members to do as follows:
- Issue a statement to disregard the Thaksin regime and officials serving as its lackeys;
- Erect signboards to disapprove of the Thaksin regime and such officials;
- Display a sign of civil disobedience against the regime by affixing a national flag or other symbols on their vehicles or workplaces;
- Join PDRC's operations on May 19-21 to retake state power; and
- Go on a work stoppage from May 22.
"If the government does not return power to the people, we will resort to stringent measures with our tools on hand to bring victory to the people.
"We call for the government, particularly the remaining ministers, to resign and return power to the people as soon as possible," he said.
Mr Komsan said the confederation would not resort to cutting power or water supplies.
