The biggest advantage of WFH is that you can do things at home at any time, and you can arrange your own life and work. You don't have to get up early to eat and commute, and basically sleep until you wake up naturally. For some female colleagues who have just been confined or pregnant, it is really a good way to balance family and work.

Of course, there are disadvantages. WFH does sometimes bring some efficiency problems. Working from home is always a variety of idle chores, and the efficiency is not as high as in the office. In addition, WFH has no distinction between life and work. Often unconsciously (especially for people who are more responsible or team leaders), I will write emails with my colleagues (mainly foreigners) to discuss some things at a very late time.

At the busiest time, WFH won't make you feel much better. Basically, except for eating and sleeping, you 100% work all the time. You often turn off your work computer, turn around and plunge into bed. In the morning, you open your eyes and read the email first. Can I say that the worst time was working overtime for three weeks in a row? Working more than 14 hours a day, of course, you know how to deal with it in order not to break the law.

Later, I couldn't motivate the team with overtime bonus, so everyone had to rest. Of course, you can also calculate the digression because the busy project has little to do with wfh, but what I can tell you is that you will really experience what it means to scream from a chicken, because you spend all your commuting time at work.

Seeing that it has an impact on communication, I don't think this one has. Phone, email and lync are all smooth. However, one of the communication problems of wfh is that some instant messages or gossip in the office (in fact, sometimes people know something is very important) will be known by later people. Of course, this mainly depends on personal interpersonal communication and usual communication. People with good relationships are as well informed as at home.

However, if the bosses are usually in the office, it is suggested to go to the company once in a while and have lunch together, which is conducive to closer relations and promotion, especially at the end of the year when the salary is raised, the promotion is cut and people are left behind. In this case, face-to-face communication is much better than remote communication, and people who are always wfh will indeed be marginalized in these links.
