There are experiments with duration of the working week such as "21-hour week", "three-day weekend," "six-hour day," and others, where the official minimum working time is reduced and employees go to work or students go to school for four days a week instead of the usual five days a week. This distribution of working hours can be referred to as flexible working hours. It is pointed out that workers who work one day less get extra time for hobbies, family interaction, sleep and recovery, which should have a positive effect on their productivity. In addition, operation and environmental costs are reduced, because the workplace or school is used one day less.
A decrease in the required duration of working time can lead to an increase in labor productivity, the emergence of new jobs (due to shift work) and accelerated technological development for the necessary automation of tasks that can be transferred to robots. Also, there is the idea of getting possible environmental benefits
, such as reducing vehicle emissions and diminishing energy costs in the workplace.
In order to include this practice in life, it is necessary to engage the government in adopting an appropriate legislation.
