Abusive Drunk Manager at Airbnb

My relative works with Airbnb as a fully remote worker & thus was at my place for a few days & sobbed his heart out. There’s a super boss who’s abusive at work calls & just when i was about to tell him to chill & cope it, I was told the super boss was drunk at the call. My relative has never been a slack worker & has had multiple promotions at his previous company but it seems he’s close to a nervous wreck He’s close to depression now thanks to this super boss and contemplating putting his papers. The immediate boss of my relative has asked my relative to cop it & said that it’s just part of the job & wants my relative to continue in his role. I was wondering how well known companies like Airbnb has this culture?
