For most employees, the last few weeks of December are dedicated to holiday parties, time off, or low-productivity days in the office. Very few people schedule meetings because no one would attend and those who are available often work on low-priority tasks. When not at work, people are traveling, enjoying festive events, or simply relaxing. It’s no wonder that upon returning to work, some experience a case of holiday hangover. Mild or more severe, we all need a minute to get back into the swing of things.
