This research paper explores the benefits of a four-day workweek that may affect productivity, self-satisfaction, and life expectancy. We will be using data on a country-wide scale from 25 first world countries over four continents. We will perform regression analysis to investigate the impact of a four-day workweek. The data will be collected using free and public sources published online like Our World In Data and Statista, which include GDP per capita, life satisfaction rate, human development index, and annual working hours. The results of our research and analysis will show how each independent variable will affect the dependent variable of our study, as well as any correlation between them. We aim to uncover any benefits of switching to a four day/eight-hour workweek and support the move for companies to reconsider the traditional five day/eight-hour workweek in hopes of improving the quality of life of working adults. Our results show that Human Development Index, Gross Domestic Product has a p-value of more than 0.05, and therefore we do not reject the null hypothesis that the four days work week has no impact on productivity in the workforce. Life Satisfaction Rate on the other hand has a p-value of less than 0.05, thus rejecting the null hypothesis that the four days work week has no impact on the satisfaction rate of the workforce.
