Leave and permission: two buttons, one flow

Annual leave is measured in days, a couple of hours for a doctor’s appointment in hours. Everything else is identical: who asks, who approves, how it lands on the timesheet.

The type carries the difference, not a separate table

Every type has a unit — day, hour or minute. The panel shows two buttons, but behind them is one list and one flow. Two tables would have meant writing the approval logic twice and keeping both correct.

• Whether a type consumes the balance is a property of the type
• A business trip does not consume leave, but still counts as worked
• A company can add its own type — "bank errand", for instance

An approved request reaches attendance too: no absence and no penalty is created for that day, and for an hourly permission only that window is adjusted.
