The Korea Enterprises Federation submitted 19 legislative proposals to the National Assembly on the 10th, grouping them into measures requiring swift passage, pending bills warranting careful review and legislation that should be introduced quickly. The federation urged prompt consideration of a mega-region special zone law introduced last month to encourage corporate investment, including a white-collar exemption from the 52-hour workweek cap for research and development and other staff. It also sought supplementary legislation before the revised Trade Union Act, known as the yellow envelope law, takes effect in March. KEF said the amendments should clarify employers as parties with decision-making authority over working conditions equivalent to that of the employing business owner, while excluding profit distribution and staffing or reassignment decisions arising from high-level management judgments from the definition of a labor dispute. The federation called for careful review of a statutory retirement-age extension and a worker presumption rule for people in special employment arrangements, proposing re-employment after retirement as an alternative. It also backed measures to streamline workplace-rule amendments for pay-system overhauls and improve strike authorization votes. Standing Vice Chairman Lee Dong-keun said KEF would continue presenting business concerns through relevant National Assembly committees and called for tax support for investment alongside measures to prevent leaks of core technologies.
