Can I get fired for not showing up to schedualed shift even though I told my boss Im not going to be able to come in?

The 16th and 17th Im going to be over 4 hours away from my job and theres nothing I can do about it, so if I do get schedualed those days even though its impossible for me to come in, can I get fired for that? I live in wisconsin, and work for red robin.
