Toxic manager in my new work.

I haven’t signed a contract yet, but the manager’s behavior is very toxic. He speaks disrespectfully about clients, constantly asks personal questions, and wants to know everything about employees. I’ve tried to stay calm, but I feel anxious every day before going to work. After only one month, I already feel miserable in this environment.

do I have to leave ? Is it normal for a manager to talk with “klam zayed” with juniors ? Work is 9 hours a day with 30 minutes break , my problem that is I don’t see myself staying here I hate every morning and I hate every Monday I just wanna quit .

I feel really anxious and I can’t even focus on anything and I have to decide cause I did other interviews , are toxic managers the norm ?
