New Mexico state government employees are working significantly more overtime for the 2013 budget year and it's adding up for taxpayers. Figures released in December show the state paid out nearly $36.7 million in overtime, representing nearly 1.6 million hours. The Albuquerque Journal reports the state paid out a total of $24.4 million for roughly 1 million overtime hours in 2010. The state's personnel director says the rise in overtime is due to an aging workforce and a spike in retirements.
