“Joseph Casias, 29, has sinus cancer and an inoperable brain tumor. Despite his condition, he has dutifully gone to work every day for the last five years at a Walmart in Battle Creek, Michigan, where in 2008 he was named Associate of the Year. Casias is also a legal medical marijuana patient under Michigan state law. He uses marijuana with the recommendation of his doctor to relieve the effects of cancer. … Last November, Walmart fired Casias because he tested positive for marijuana during a routine drug screening. … To add insult to injury, Walmart is now challenging Casias’ eligibility for unemployment.” (03/12/10)
