<prompt> Human: So to begin, Im just a 16 year old kid that got a job so I could pay off my grandpa who lent me money to buy a car. I live with my single mom and my sister who isnt old enough to stay home alone yet. I decided to go with McDonalds because I know how flexible their scheduling is. During my interview, I made it clear that my mom works often so the schedule flexibility is a necessity to me. Anyways, a few days ago my mom got demoted at work and now she has to work every Saturday, which means my sister has to be watched one way or another. So when I went in to work yesterday, I asked my hiring manager the one that knows my situation for Saturdays off from now on, and she told me to speak to the General Manager. So I spoke to her today, and she told me theres no way I can get Saturdays off I work Friday, Saturday, and Sunday every week. So now my sister is going to be unwatched my grandpa can watch her every so often, but not every week, and I have no time to do my school work over the weekend. I told my GM both of these points and she still said its impossible to get Saturday off until maybe 2016.Now, my question is, is my only option to quit? I need a job pretty bad so I dont really want that to be my only option, but if it is, so be it.TL;DR: 16, work Friday, Saturday, and Sunday. My mom got demoted and it changed her schedule at her work, so I have to watch my younger sister on Saturdays. G.M says its impossible to get Saturday or any weekend day off. Do I have to quit?  <response>: They are allowed to set your work hours. If they wont budge, then yes, quitting is your recourse.
