When we talk about not being at work, there are a variety of synonyms we can use to describe the situation. For instance, "on a break" could be used to imply that time off is temporary, while "away from the office" is a non-specific way of referring to time spent not working. "Out of the office" or "out of the workplace" are similar in meaning and also suggest an absence from work. "Taking time off," "absent," and "non-working" are all straightforward ways to say that someone is off work. Using these synonyms can help to add variety to your language, as well as clarify the context of the absence.
