Broke the law - Crew Member Chipotle Employee Review

After 4 shifts, I wasn't on the schedule for the next week. I asked why and was told that nothing was wrong and that there were simply not many hours to go around. After 4 weeks of not being on the schedule, they fired me. I put them as a reference for my next job because I figured they couldn't say anything bad about me since I was only there for a small time, and my friend told me they said that I complained about things and that's why they fired me. This is libel and it's very illegal. The only thing that former employers can say about you is whether they'd rehire you. 0 stars this place never communicated anything to me and just fired me.
