I'm going to actively steal from my boss
Did your boss do anything to you to make you feel this way towards him?
Yeah he didn't protect me
Not all bosses are saints, and it can be real frustrating to deal with them. But this is your workplace and livelihood, so I don't think it's worth it to do something illegal that can jeopardize your life.
I think my brother's boyfriend thinks it's okay and he's a boss too. I don't care if it's not right. I need to make sure that my boss learns what wrong he is doing, and to be nicer to the rest of the employees.
Keep your family dynamic out of the workplace. You can't abuse your relationship with him to benefit yourself and think you will get away with it.
