United Continental Holdings Inc on Monday announced the appointment of an interim leader four days after Chief Executive Officer Oscar Munoz suffered a heart attack.
United says general counsel Brett Hart, 46, would take on the role of acting chief executive officer, effective immediately.
The airline said it was too soon to tell if Munoz would return to the job he started only several months ago.
In a press release Hart said he would move forward with an agenda set by Munoz that has been aimed at rebuilding the company’s morale after years of strained labor relations.
United, the second-largest U.S. airline by capacity, said in a statement that its board “remains actively engaged in preparing for all potential outcomes regarding the company’s leadership structure.”
Hart will address investors on Thursday when the company releases its third-quarter results.
Before joining United in 2010 Hart worked in the same role for Sara Lee Corp, a consumer goods company.
Munoz took over the CEO in September. He spent his first month traveling around the United States, meeting with workers and asking for their input on how United could improve.
On October 15, Munoz suffered a heart attack. His family has since said he is expected to make a “healthy recovery.” They have not revealed any further information about his condition at this time.
Analysts have criticized the company for not providing enough information fast enough about its CEO.
