How do I see who's on site?

Open the Site Attendance page. The Attendees list shows who checked in today, and anyone with no check-out time is still on site.

Steps

In the left menu, under Field Operations, click CheckIns, then click Site Attendance. You can also click Site Attendance > on the Dashboard.
Read the summary cards at the top: Check-ins, Away, Suspicious Check-ins and On Leave.
Look at the Attendees list. Each person shows the project, their check-in time (green arrow) and check-out time (red arrow).
Anyone whose check-out time shows --:-- -- hasn't checked out yet, so they're still on site.
Click a person's name to open their profile and check-in details.

Absentees are people who didn't check in. An orange On leave badge means they're on approved leave.
To look at an earlier day, click the date button in the Project Sites panel and pick a day. You can't pick a future date.
Type in the Search app user box above a list to find someone. Each list shows up to 30 people at a time.
Site Attendance may appear directly under Field Operations instead of inside CheckIns, depending on how your account is set up.
To narrow it to one site, see How do I see attendance for one project?

No attendees for this date. or No absentees for this date.: nobody matches the date, project or company you picked. Try another date or click Clear Filters.
The project menu items in Field Operations only show once your account has at least one project.
