Can 4 working days a week achieve same result as 5 working days a week? 
 Firstly 4 day work week is not working overtime for the same hours over 4 days. Rather it is generally defined as reduced working hours. It has tried in different parts of the world on an experimental basis and a few of the organisations have adopted it permanently. Reducing working hours is not a completely a new idea. Over the last century, the working hours have been reduced and it has benefited employees as well as employers. A few key benefits include reduced burnout of employees, higher productivity, reduced carbon footprint and less number of absences. It can also help attract talent in the job market. However it can increase cost of the employer. In addition, it may not be suitable for all industries or employees. in summary, it is one of the viable option and based on the industry, it might be adopted further in the near future.
