Question: 2nd job demanding to be primary?

I work as a federal mapping engineer and 2nd job as a meter maid, my second job demanded me to put them as priority and I told them no, that is not in my best interest and I will be facing the music this weekend. Should I resign before I get fired? I filled out a form with HR stating I have 2 jobs at the beginning of my employment so where is this coming from? Can they actually legally do this?? (City)
