Study Finds Morning People Are Happier

BERLIN, GERMANY – JANUARY 10: An alarm clock meant to symbolize the demand for workers to better determine their working hours stands near where workers from nearby Daimler and General Electric production plants were participating in a strike in demands for better pay and more flexible working conditions on January 10, 2018 in Berlin, Germany. The strike is part of dozens nationwide organized by the IG Metall labour union, which is pressing employers for a 6% increase in wages and the option of a limited, two-year 28 hour work week for workers in particular circumstances. Employers counter the demands would require them to hire at least 150,000 more workers at a time when the German manufacturing sector is already struggling to find qualified workers amidst low unemployment. IG Metall is the world’s largest labour union and has 3.9 million members. (Photo by Sean Gallup/Getty Images)
