- **WTD Pay (+12.07%):** Working Time Directive rolled-up statutory holiday pay paid on NHS Staff Bank shifts.
- **Why PAID/DUE Hours Are Smaller Than WKD/EARNED Hours:** Because basic daytime pay is already included in your monthly Basic Pay line, ESR multiplies your unsocial hours worked by the enhancement percentage (e.g. 34.50 hours × 30% = 10.35 PAID/DUE hours) and pays those fractional hours at your plain hourly rate.
