Sin Sung Chol, chairman of the KCTU, at the rally held at Seoul Square declared workers would become permanent slaves unless they fight against the present "government," which tramples down their right to existence.

He called for dynamic actions to punish the present "government" keen to sell public sectors to the plutocrats.

The KCTU will launch the third action across south Korea on Jan. 18 and go on a general strike for the resignation of the regime, frustration of the suppression of the labor movement and a halt to privatization in connection with the lapse of a year since Park Geun Hye's coming to power, he added.

Earlier, the headquarters for general strike of the KCTU held a meeting on Tuesday at which it declared there is nothing to expect from the present regime hell-bent on the suppression of the labor movement.

The former central executive members of the KCTU held a meeting in Seoul on Wednesday at which they denounced Park Geun Hye for revealing her attempt to push ahead with privatization of public sectors at her New Year press conference.
