Why does salt make the floor slippery?

Steven King asked the Naked Scientists:
Hello Chris,
My question concerns why the floors at my job are very slippery after a snow/ice storm.  I know they sprinkle salt outside to remove the ice, but why does that cause the hallways to be extremely slippery for days after the ice is gone outside?  They don't use cinders outside, only the sidewalk salt. The floors inside are dry, but very slippery.
Thank you for the great podcasts!
