Is there a rule that the front desk must work at night to collect property fees?

This is just a different division of labor within the property company.

See if there is a clear division of labor between the project manager and the department head. In general, customer service personnel are the mainstay, supplemented by various departments.

As for the night shift reminder, it is not recommended in principle. On the one hand, it will exclude the landlord/tenant, on the other hand, the front desk staff are mostly women, so it is not recommended for safety reasons.

Like the specific rules, there are basically not so many regulations.

I hope to give you a reference.
