Workers in the 19th century spent an average of 60-70 hours per week on the job or 3000+ hours per year. The workers in this group were mainly men, and they didn't have much free time outside of work. The work culture in those days was interesting. People usually worked at one company for their whole lives. Despite job security, there was a lack of work-life balance, and there was a noticeable gender gap.
Up until unionization, this trend persisted. Employees began seeking improved working conditions. We now enjoy the 40-hour workweek because of a long struggle. Gen Z workers can't even relate to working 60 to 70 hours per week. The human race has made progress, but it's time to advance even further.
Four-day workweeks are the next step. The 100-80-100 formula can be simplified to mean 100% pay for 80% of the time in exchange for 100% productivity. Employees are benefited from this flexible principle. In a company, the workers or a particular team has the option of either taking a day off or working truncated hours for five days. Employees are free to make their own choices as long as the company will meet or exceed its bottom line.
The gig economy may appear similar to the 4-day week, but it isn't. They are quite different. Although the gig economy promises flexibility without the added benefits of a traditional job, the four-day week is the traditional job with all its benefits plus enormous flexibility. You should choose the 4-day work week because it means that your employer will give you flexibility, but also will be required by law to provide you with work leaves, 401Ks, and other work benefits that your local law requires.
Any team you're a part of is impacted by your personal productivity. Take advantage of time blocking to increase your productivity. Block out time when you'll only focus on working without distractions. You could also schedule a "distraction-free" time. You can call it whatever you want, but essentially this time is for all the distractions that usually interrupt your work. As such, when it is work time, you focus exclusively on work, and when it is a distraction or break time, you do whatever you like. You should limit your distraction time, however.
