When was the last time you took a vacation? And not a business trip or a long weekend for your cousin’s wedding — a real vacation. If you can’t remember, then you’re probably suffering from burn out, and you’re not the only one who had a rough 2017. Today’s workers are often impacted by a culture of overwork, wasting vacation days to achieve more. If you identify with this mentality, you might be doing more harm than good to your health and productivity.
