How about working three days a week? In most countries of the world, people work five days a week and rest two days at the weekend. Some have suggested that it would be more enjoyable to shorter the working days. But will three days a week with longer working hours benefit more for employers and employees? In my opinion, shorter working hour per day works much better. First of all, the process of many works such as business, construction, medication or education etc., needs to be continuously followed up. If the employees work three days a week, the project will be postpone for four days. Then the whole period of the project would be extended which means higher costs would be invested. For instance, although the doctors in hostpital work hard and for more time during his working hours, the patients cannot recover in one day. What if the patients have new symptoms during the doctors day off? In this case, the doctors may either break his vacation going back to their patients, or have low effective results on their medical work. Also, longer working hours per day brings increases stress levels on the employees. When adding working hour at the work day, the relax time would be cut short. As we all know, our brain and mussles need to relax after one or two hours of concentrating. Or very we will get tired and become easily distracted from work. So it’s improtant to keep a good condition for our body. Working days a week means adding 6 hours to the regular 8 working hours. This high intense challenge will brings damage to the health system of our body. Thus, the employees have more pressure at their work day and the work effeciency would be largely reduced. Most importantly, less working days and more rest may not enjoyable at all to the entrepreneurial world. To people who enjoy their job very much, they want to work almost everyday and invest as much their time as possible to their career. A longer weekend may be a disadvantage for their business. So for more enjoyable at work, people would expect other ways such as change office environment, or make working location flexible. To sum it up, even though longer working hour sounds attractive because it release more days to the weekend, the costs from more working hours per day over the benefits. If we consider people’s healthy and work efficiency as improtant, obviously, working five days a week for shorter hours per day would be a better choice.
