This bill is basically giving collective bargaining rights to sub-contractors and those not directly employed by businesses. What is probably the most interesting aspect of this bill is that unions get protections from causing damage to businesses while protesting. Considering how violent the KCTU can be when protesting, it is likely them who advocated for this protection in the bill:

Korea’s contentious pro-labor bill — dubbed the “yellow envelope bill” — was approved at the National Assembly on Sunday, after nearly a decade of political tug-of-war.
The ruling Democratic Party of Korea (DPK) railroaded the passage, with 183 votes in favor and three against out of 186 lawmakers present, mostly DPK and minor liberal parties. Members of the conservative main opposition People Power Party boycotted the vote, following a 24-hour filibuster that ended earlier that day.
The new law, an amendment to Articles 2 and 3 of the Trade Union and Labor Relations Adjustment Act, aims to broaden workers’ rights in collective actions and negotiations with employers. It will take effect six months after promulgation.
Under the revision, subcontracted and indirectly employed workers will be able to negotiate directly with parent companies on issues in which the parent company wields effective control, such as workplace safety.
The legislation also expands the scope of labor disputes to include restructuring and mass layoffs, though not all business decisions — such as overseas investments — automatically qualify. In addition, unions and workers gain protection from some damage suits for losses resulting from labor actions, especially those taken to defend their rights against an employer’s unlawful conduct.
