What term describes time spent away from work, usually for illness?

The term that describes time spent away from work, usually for illness, is best defined as leave time. Leave time refers to the period an employee takes off from their job to deal with personal matters, including health issues. This can encompass various types of leave, such as sick leave or medical leave, specifically intended for when an employee is unable to perform their work due to medical reasons.

While user time, illness time, and rest time might intuitively seem relevant, they don't specifically capture the formal categorization used in employment contexts. User time is not a standard term associated with time off from work for medical reasons, illness time may suggest a more informal phrasing, and rest time typically refers to breaks taken during work hours rather than extended time away due to illness. Therefore, leave time is the term that accurately encompasses the concept of taking time off work for health-related issues.
