If you're not going to be able to stay with them and keep an eye on her, I would leave her in her own cage until you got home for the day. She'll be sleeping it all off anyhow, so just make sure she's got lots of cozy spots and a treat or 5. After you get home, you can pop her back into the cage for the rest of the night. You'll be closer to hand if anything happens or someone gets a little too pushy with her.
