CHICAGO - Nearly 100 workers had to be evacuated from a Near North Side postal facility and nearly a dozen were taken to area hospitals after the building got so hot and humid workers said it was like "working in an oven."
A US Postal Service spokesman on the scene says that the air conditioner was not working and the workers became overheated.
Workers said they're concerned the problems will not be fixed, and they often have to endure extreme temperatures in summer and in winter.
At least a dozen workers were treated for heat stress, heat stroke, and dehydration at area hospitals. Postal Union spokesman Mack Julion says they are looking into the working conditions at this location.
The River North Post office will be closed today.
The Postal Service says mail will likely be disrupted through Monday for the following areas: 60610, 60611, and 60654.
