Medical marijuana is legal in Michigan but WalMart claims it has the right to fire anyone who uses it anyway. When a routine drug screening detected marijuana in his system, Joseph Casias was fired as a matter of policy.
Former WalMart Associate Of The Year at the WalMart store in Battle Creek, Joseph Casias, showed them his medical marijuana card to no avail. "I was told they do not accept or honor my medical marijuana card," says Casias.
"I gave them everything," he says. "110 percent every day. Anything they asked me to do I did. More than they asked me to do. 12 to 14 hours a day."
WalMart spokesman Greg Rossiter explained, "In states, such as Michigan, where prescriptions for marijuana can be obtained, an employer can still enforce a policy that requires termination of employment following a positive drug screen. We believe our policy complies with the law and we support decisions based on the policy."
Sorry Joe. At WalMart you're not a person. You're just another employee number.
