By 2020, more than half of the workforce will be Millennials, and the things that inspire and engage these young workers are completely different from those employees who are 10 to 20 years their senior. This looming generational shift has some companies worried, but other organizations are already preparing for how they will engage the next wave of workers. One of the most basic concepts to understand in developing an engagement program for Millennial workers is that need drives engagement. If a company can demonstrate that they can address the needs of the worker, that worker is more likely to be engaged. This means Millennials are looking more closely at training and development programs. In a recent study published by Mindflash, more than 20 percent of Millennials surveyed said interpersonal communication was the top area where they wanted training. Another 26 percent said they were more likely to be engaged if it was clear their employers were looking to invest in their careers by training them.
