First of all, you are definitely right about this.

The problem is that your manager has only verbal demands but no specific disciplinary measures.

This is the deadliest thing in management.

You as a staff member have almost no say in this matter.

You are introverted, and the male boss of Teppanyaki sees that you are easy to bully and makes things difficult for you many times, but there is nothing you can do.

His behavior is the bad root of a small group of people, which is bullying the weak.

Secondly, don’t stay in a state of self-blame and entanglement.

You must learn to speak out, learn to say no, and learn to control your emotions.

Just saying it proves your attitude.

Do not think too much.
