It seems pretty clear that the brother is trying to sideline her because of the bad publicity her presence would bring. With that said people need to get over the whole “nut rage” incident. She was vilified, sent to jail, lost her job, humiliated, and then even divorced by her husband. I think she has been punished enough for turning a plane around at the airport:
Cho Hyun-ah, former Korean Air executive vice president, accused her younger brother Monday of not leading Hanjin Group in accordance with their father’s dying injunctions, signaling a sibling feud over control of the logistics-centered conglomerate.

Cho, who is notorious for her 2014 “nut rage” incident, released a statement via her legal representative, claiming that Hanjin Group Chairman Cho Won-tae is not following their father’s instructions regarding group management.
“Our father wanted the family to run the business together, but Hanjin Group is currently neglecting his last words,” Hyun-ah said through her legal representative.
Former Hanjin Group Chairman Cho Yang-ho died of a chronic lung disease in Los Angeles in April at the age of 70.
Their feud surfaced in May when the board of Hanjin KAL, the group’s holding company, belatedly named Won-tae as the group’s new chairman reorganized by the Fair Trade Act. Hyun-ah and her sister Hyun-min allegedly disagreed with their brother.
