So I have a very unconventional employment situation. I am the partner of a live-in nanny. We both moved across the country with the family she Nannys for. They asked her to move with them without me and she refused because that would have been the end of our relationship  and would have screwed me over on the lease we had just signed.

 The initial agreement was that we would live with then for two months then move out. But we have lived with them for 4 months now. They never discussed increasing my partners wage due to higher cost of living and refuse to. They also have hired me on at a higher hourly rate to help with maintenance around the house and filling in to watch the kids. 

Even though they pay me more than my partner, I only ever work ~4 hours a week (they make sure.) Well today is payday and I asked to be paid about 12 hours earlier than usual because I have a bill due before my normal pay time and wanted to make sure the money would be in my account. They are refusing to pay me until tomorrow night when I help them host a party (not something I ever agreed to do or even discussed with them) which will mean my bill is paid late and will probably incur penalties. 

My partner isn't in a position to help because she gets paid half of what I do and uses most of that money to feed us. 

So even though I live in my employers house for free, am I the asshole for wanting to get paid early on my own terms?
