Establish an international convention that delays Monday business hours by a few hours so that people can start their weeks on a pleasant note.
Weekends are generally associated with freedom, so people look forward to them. This can't be said for workdays.
In spite of the fact that people have to work on Saturdays, they still experience a "weekend feel" because business hours are shortened on Saturdays. At the very least, Saturdays are an extension of work-free Sundays.
What if Mondays began on the same note as Sundays and extended Sundays in the opposite direction? People wouldn't have to wake up with alarm clocks if business hours started later. They could spend Monday morning with their families and then ease into the workweek.
It's only a few hours difference but would have a big psychological impact on society. The economy wouldn't suffer that much. Things would still get done on Mondays, only they would have to be better planned.
People have gotten used to less convenience in Covid times. Nowadays it shouldn't be a problem to wait a few hours to get things done on Mondays.
