While commonly associated with headaches, migraines can be so much more debilitating and include light and sound sensitivity, severe nausea, and a range of other symptoms that can make those experiencing them shut down for anywhere between a few hours and a few days. HR managers should be particularly vigilant in addressing this issue in the workplace because in the United States, 18% of women and 6% of men experience migraines. The fact that they are so misunderstood creates a number of serious workplace issues that are easily avoidable with the right information.
