Is this normal?

Hello, I recently just got hired. Well about a 2 1/2 months ago. I’ve only been scheduled ONE DAY A WEEK! And looking at our schedule I noticed that the manager is scheduled 48 hours every week. On the one day I do work, I heard that the manager is hiring his old team from Rite Aid, and that we are “sharing” hours with others from a different store. I’m honestly wanting to quit because one day a week isn’t gonna help pay my bills and it’s hard to schedule other things I do for income like Amazon Flex because I don’t know when my one day is going to be scheduled. Is this normal? The problem is a friend helped me get in. I feel horrible for telling the manager off because I don’t want him to go after her. I don’t think he will.
