Of course, your work day can’t possibly be the same, and while I admit I initially laughed at a Google employee who asked about how to get morning coffee, his experience is not unusual: Your routine will change, and you will need time to figure out how to accommodate those changes, like making coffee at home if you’re used to picking it up on the way to work.

As for what to wear in your home office, I am squarely in the “be comfortable” camp, though Barbara Pachter, author of “The Essentials of Business Etiquette” and a longtime work-from-homer, said that in the beginning, you should get dressed as if you were going into an office. It will help in giving some structure to your day, and you can change your home dress code later, as you adjust to your new working arrangement.

Set Boundaries

Pick a spot for your office. It doesn’t have to have a door, but it should be away from distraction. You don’t need an expensive set up. I have an office, but I’m much more likely to write at a stand-up “desk” I’ve fashioned with a stack of books on my kitchen counter.

The boundaries you set up also pertain to other people who may be sharing the same space. This will be especially important if a partner or roommate is also working from home or children’s schools are closed. Ms. Pachter suggests that if kids are given assignments to do at home, they work alongside their parents as if they were coming to the office with you. (The effectiveness of this may vary, depending on your children’s ages and needs.)

But being expected to work from home full time while also home-schooling children full time is just not going to be realistic, said Sara Perry, assistant professor of management at Baylor University. “There’s a lot demanding of your time and energy and resources right now,” she said. This may mean having conversations with managers about adjusting their expectations, given the extraordinary circumstances.
