Anything to do here?

Hey everyone, we have a fairly new GA who calls in to at least 75% of his shifts and no called, no showed two days in a row but still keeps getting scheduled and its almost always when I work with him. My SL doesn't really care because it doesn't affect him. Is there anything I can do about this besides grin and take it? I don't have any decision making when it comes to the scheduling process either.
