The Activity tab on My Pay & Time shows the same activity feed as your employee profile — it's the same feed, just reached from a different page. Despite sitting next to Earnings and Commission Rules, it doesn't log compensation (pay type or rate) changes specifically.
What's logged
Profile field updates (hire date, status, notes, emergency contact), department changes, employee type assignments, commission rule create/update/delete, role changes, and comments team members leave on your profile. Use the filter dropdown to narrow to one category, or a date range to scope by time.
Admins viewing another employee
An admin can switch whose Pay & Time they're viewing using the selector next to the page title — a banner reads "Viewing [name]'s Pay & Time dashboard (Admin View)" while doing so, and the Activity tab follows whichever employee is selected.
