Job performance and chemical dependency : a practical guide for managers and supervisors / Lynda A. Voorhees and Robert B. Maddux.

"Job Performance and Chemical Dependency is not like most books. It stands out from the other self-help books in an important way. It's not a book to read it's a book to use. The unique "self-paced" format of this book and the many worksheets, encourage a reader to get involved and, try some new ideas immediately."--From page i.
