Trending @Accenture; People Lead Issue

My so called people lead or manager does not even reply to junior's greetings or good morning.she talk only with managers who are either on her level or above.infact she got promoted in June and threw a party in which no one from her team or junior's who visit office and sit in same bay as she was invited. Only people with the same level as she are or higher. She is toxic and arrogant asf.

What is your issue ?facing some issue myself
