SEOUL (Reuters) - Korean Air Lines' unions have called for the youngest daughter of its chairman, a sister of the infamous 'nut rage' heiress, to step down from management after her alleged abusive behaviour against an advertising agency official caused public outrage.

Cho Hyun-min, also known as Emily Cho and a senior vice president at Korean Air, apologised on Thursday for what she called her "foolish behaviour" after media reports said she threw water at the face of an advertising agency manager during a recent business meeting.
