The National Union of Media Workers says it will begin an indefinite general strike on Friday against the seven controversial media laws sought by the ruling Grand National Party.

The union leadership said unionized workers will launch the strike on Friday morning and hold a protest rally in the afternoon on Yeouido in western Seoul.

In a news conference Wednesday, the union urged the GNP to stop trying to pass what they called "evil laws" that would allow newspapers to own broadcasting companies.

The union argued that if passed, the laws would allow large corporations and big conservative newspapers to control the media.
