You may need to find a more succinct approach to deliver your message, whether at home or in the workplace.
Sometimes there's a lot to say but not enough space or words. This is when jargon and acronyms come in handy.
You may need to let your boss know that you'll be out of commission (or "OOO") for the next week and hence unable to contribute to the major project.
Alternatively, you may need to notify your colleagues that you will be "AFK" due to lunch.
Working from home, or "WFH" as the acronym is abbreviated, is working independently from a traditional workplace.
This phrase is used to indicate that the speaker is not physically present at the workplace but is instead doing his or her duties from home.
It may be used in a variety of contexts, such as when someone is home ill or when discussing a position that does not need physical presence.
