A corrections deputy was arrested for driving under the influence of intoxicants near his home. The arrest was without incident, and resulted in a diversion agreement instead of a conviction. The employer imposed a long suspension as the “minimum” discipline available under its guidelines, and the deputy’s union grieved the discipline. Hank Kaplan, representing the union, established that the employer’s past practice was to impose a single-day minimum for similar offenses, and the arbitrator agreed. The discipline was changed to one day, and the deputy was made whole for the difference.
