We use many to one all the time, because Many to one is a one to many relationship with different view point.

Examples:

[Department to Employees] is one to many and [Employees to  Department] is many to one  

[Customer to Orders] is one to many and [Orders to Customer] is many to one  

The common viewpoint to this kind of relationships is the one to many.

Hope this help
