More than 100 moms and dads (and grandparents!) joined us in our office the first year, and more than 150 showed up for the second. Coming to Chicago from as far away as New York and San Francisco, these engaged "olds" (many of whom were, sadly, about my age) joined their kids for a half-day program comprising media agency basics, a parenting panel, a job shadowing segment and one of the most rip-roaring happy hours in agency history. Want to engage and retain your millennial employees? Maybe start by wooing their parents.
