New at Amazon-Time Off?

I start at an Amazon warehouse on the 20th of this month as a Part Time associate. I had a family reunion scheduled out of state long before I applied that will require me to take 4 days off in what would be my 3rd week there. I’ve not had a chance to talk to anyone at Amazon about this yet and I’m concerned it will be an issue. Does anyone have any insight for situations like this? Do new hires have the opportunity to take unpaid time off like this without causing issues?
