My dad is picking on me and it's giving me the urge to leave work early.
Has your dad picked on you before?
Yes, because I felt burned by him in the past. The little shit really pissed me off.
Your father has picked on you many times and today was no different. It's understandable that you would not want to be at a workplace that belittles you.
My dad already apologized for it. I don't hate him.
I'm glad your father apologize to you. But I would have a conversation with them that this is really upsetting you. That way you no longer feel you need to leave the workplace because of him.
