Problem involving family and work oppurtunity?

I'm only 14 and I work every other week end at a hairdressers as an assistant, and recently, the other assistant who works when I'm not in has quit. This means there will be a new slot open or my work has offered me the opportunity of working every weekend. My auntie is going to America in July and would really like the extra money to spend there; so she asked me if I would recommend she takes the slot. Is it unfair for me to take the opportunity from her? Our family is telling me to recommend her but I feel they have her best interest at heart and not mine. I'm trying to build up my trust fund for oxford and I could do with the extra money too. And I know it might sound very silly, but she always has to have everything I have. I get a iPhone, she gets an I phone; I go to New York; she has to go to New York. Obviously not a competition that I want, but I can't help feeling that it's there? Is it pathetic for me to want to keep this for myself? I'm unsure what to do, any advice?

I would take the job. Your aunt kind find another job. She's probably an adult, I'm assuming. So she shouldn't take that opportunity from you. Don't let people make you feel guilty for looking out for yourself. Your family should understand.
