When going to School > Timetable > Timetable Settings > Staff Names, you will only see staff members who have a teaching role. This is because:
- Teachers are typically those that will have timetables where they interact with students regularly.
- Non-Teaching staff typically won't have their name appear on student timetables, so won't need an abbreviation.
You can see who will appear in the Staff Abbreviations section here: Which business roles are classed as Teaching Staff?
