Core Data getting many data from relationship.

I think this is a very basic question and I'm just not finding the answer. I want to get the many data for a given relationship. Lets say I have a Department and I want to get all its Employees. Department has a relationship called employees. Is this what I do?

id result = [aDepertment valueForKey:@"employees"];

What do I get back? Is it an array, a set, or some other kind of container?

Should I be using mutableArrayValueForKey from NSKeyValueCoding protocal?

I have been reading the Core Data docs and all the examples show situations that return only one object.

thanks for the help
