Just curious, at what point does a person get fired for absenteeism?

Myself and another coworker has been here for 2 months. This coworker has been absent for a total of over 2 weeks in that span.

Said person just moved to this state as well.

Has been out for multiple reasons, including car problems, the death of a cousin
( I didn't know you could have 5 days of bereavement for a cousin).

Now said person is having problems with the new house, and hasn't been to work since Tuesday of last week.

If it were me, I'm sure I would have been fired.
How does said person still have a job?
