Well, working from home actually offers more convenience for workers. No need to wear formal attire and no need to travel and spend money and time. However, despite of its advantages, there are also some noted reasons why working from home become less efficient and less productive. There are these home life distractions that will lessen your focus on your job and as an outcome, your work becomes affected and compromised. Also, the fact that you are less monitored by your heads or supervisors, makes you more less motivated to your work and put your own job at a risk. Nonetheless, the things that I mentioned may not be applicable to all workers/employees since each of them has different working condition.
I've been working from home for a while and I do agree with the research, but there's a catch. There's a huge difference between people who worked from home the whole time and people who were moved from office to their homes during the pandemic and stayed there because it was more convenient for the company. People who always worked online are used to it and they can focus on their tasks.
I have a friend who used to work from the office and he told me that the company offered them bonuses to stay home because they had saved so much on electricity that they could give everyone a raise and still make more money. If I were him I'd also take the raise and stay home.
