Didn't Moon Jae-in do a good job improving corporate job security, workplace culture, and work-life balance?

‌‌Even before Moon Jae-in took office, many people said that working for a public enterprise was better than working for a large corporation, because even in large private companies, job security was unstable and work-life balance was poor. However, looking at how the culture in large corporations has improved under Moon's administration to enjoy high wages, job security, and work-life balance, even if he was incompetent in other areas, didn't he do a good job specifically with strengthening labor laws and improving job security and work-life balance?
