These researchers found that if you work from home you will be less efficient and productive than people who from their office. Can we say the same about freelance workers? Do you think that if workers are given the chance to "own" a task like freelancers they'll be more productive because it is just like being self-employed where you treat it as your business and not with the mindset of another man's business?
The important thing is to finish the work on time. There are companies that are not interested in what you do at home or in the office, but only in the result you produce. The cost of opening an office can be very high. Now it is often preferred to eliminate this cost and use the work-from-home method.
I think the main thing to do is to reduce the working hours in the office. Because in this way, one can work more efficiently in less time. He can also spare the remaining time for himself. If a person who has the chance to finish a job in 3 hours spends all the remaining time at the workplace, this person's productivity may decrease. A lot of changes need to be made in this regard. Many companies have started to make such changes.
