DC Hospital Will Fire Four More Nurses for Missing Work Because of Blizzard

"This has been our mindset as we carefully reviewed the events of the snowstorm and the facts we had at the time," Rider wrote. "Our process was open, so that if additional facts were brought to our attention, we re-evaluated each case."

Rider said the blizzards had a significant personal and economic impact on the hospital.

"The DC Chamber of Commerce is currently conducting a survey to determine the economic impact of the snowstorms on Washington business," Rider said. "I know that our additional expense was $2.5 million for wages, food, and snow removal."

While others had seen their business falter during the storms, "ours was actually increasing," Rider said. The hospitals' daily census grew from 675 to 740, and 90 babies were delivered.

To accommodate workers who spent the night at the hospital, Rider said the hospital "provided 7,300 meal vouchers and sleeping arrangements at various times, as best as possible, for 2,200" hospital staffers.

In his memo, Rider thanked employees who worked during the snowstorms, adding: "We were able to, once again, remind the community we are here for them and we never close."
