Boss bollocking
When her aggression expressed through sarcasm and humor, it may due to her insecurity. Stand up to your boss, who’s being verbally abusive by sitting down to talk to her one-on-one. Difficult it may sound but oftentimes helps. Many managers are not aware of the impact of their words and style, mixing up directness with arrogance. Avoid using the official reporting channels, such as compliance reporting hotline. Ultimately, give her the (fals or real) sense of security.
