The uproar that forced a Korean Air Lines executive to resign after delaying a flight because she was unhappy with the way nuts were served points to growing intolerance of corporate bad behavior in a country dominated by family conglomerates.

Public frustration has long simmered over a culture of impunity that saw bosses of corporate groups known as chaebol often evading jail time for more serious offenses. Due to poor governance and stingy dividend payouts, shares of South Korean companies trade at discounts compared to peers elsewhere.

That culture is slowly changing under the government of President Park Geun-hye, who took office last year after a convincing electoral win partly based on a tougher line on self-serving or abusive behavior by chaebol and their families.
