How do I change my kittens' jobs?

In the Small Village, I see a Census that tells me the following information for each of my kittens:

[:3] NAME NAME - JOB
age: AGE
SKILL1 (X%) job1
SKILL2 (Y%) job2

But I don't know how to get my kittens into the job they are best at. How are kittens assigned to jobs?
