Labor Laws?

What are the laws for a Salaried employees in Louisiana? Recently an employee used all of her sick time and had to miss time beyond her allotted sick time. She has yet to earn any vacation time. She missed time for bringing her son to the hospital, flu, and she had kidney stones in which she spent a day at the hospital/doctor doing tests. The extra day beyond her sick time was docked from her pay check.

The question is what are the laws regarding salaried employee's missing work without vacation or sick time to cover.

And does a company HAVE to credit K-time?
