LOS ANGELES (AP) — A report says the Los Angeles Department of Water and Power spent tens of millions of dollars on extra sick days for its employees, and some workers may have abused the system.

The Los Angeles Times says the DWP officially grants 10 sick days a year but a policy twist permits workers to take virtually unlimited extra days.

Altogether, the DWP has paid workers $35.5 million in extra sick days since 2010.

However, DWP Executive Director Ron Nichols says the average worker only takes around 4 1/2 sick days a year — about the national average.
