Employee Failed Drug Test and Filed for Unemployment Benefits

Dear Glenn,

We have a former employee who failed a drug test. She said she wanted to quit because if other employees found out, she would be embarrassed. We filled out a final release form stating why she wanted to quit and she signed it. She then filed for unemployment benefits. We explained the reason for her leaving, and the unemployment office said the paperwork was insufficient. What would you do, ask her to gladly come back to work, or what?
