In retail, we know how it can be. Sometimes you work a billion hours. Or you have to deal with the crazy black Friday customers
Do your hours change/increase and become sporadic as November rolls around? Until Christmas time?
I work at Target. The only difference for me is my schedule gets pushed forward by 5 hours (meaning earlier) and since I work logistics, that puts me into working all nighters.

So 11pm to 7:30am. It is just for 7 to 8 weeks. It's always consistent, so that's a plus! Black Friday I have to work at 9pm to 7:30am.
Sometimes I get a lot of over time too. It's allowed if granted.
