How many hours does Kaibin Century Hotel work at the front desk?

The front desk of Kaibin Century Hotel works 24 hours a day.

Last time, I worked 24 hours and had a 24-hour rest, or two people worked in shifts and one worked 12 hours. You work the day shift this month, you work the night shift next month, I work the day shift, and I have four days off every month. You can also take a vacation after taking a break. It's hard and boring anyway.
