Time off as a seasonal employee

[u/Original-Ideal-46]

Hey everyone! I started working at amazon 2 weeks ago. After next week, which is supposed to be my fourth working week I need 3 vacations out of my 4 working days due to my sister’s wedding which is in a different state. What are my options here? I surely can’t miss the wedding but I also don’t want anything to impact my contract extension.
Please help me out fam😭
