So my boss who is also my step father who is also a big fat jerk...?

I'm sick I went to the doc yesterday and I have bronchitis an infection in my throat and in both ears and I have been put on antibiotics and other meds. So I called in this morning the 2nd time in 3 years that I have called in. At 9am he calls me to say I need to come in so here I am looking and feeling like **** all day no one has called no one has come in and now I find out that I need to be here so he can be at home. He is at home!!! I am so pissed! Should I just quit? I mean find another job first and then quit OH I hate him so much what an a hole!
