Note: The “Hours paid, CES” series is all-employee hours paid in the Current Employment Statistics (CES) survey;  the “Hours worked, new” series is all-employee hours calculated using the new method (all-employee hours paid, with a paid-time-off and off-the-clock hours adjustment); the “Hours worked, old” series is all-employee hours calculated using the 2004 method; and the “Paid hours worked” series is CES all-employee hours paid adjusted using the National Compensation Survey (NCS) hours-worked-to-hours-paid (HWHP) ratio. The NCS HWHP ratio adjusts hours paid for paid time off (annual leave earned, including paid holidays, and average annual sick leave taken). Q1 = first quarter, Q2 = second quarter, Q3 = third quarter, and Q4 = fourth quarter.
