Non-emergency personnel should be off of the roads when the weather makes travel hazardous. Companies forcing their employees to travel to the office should face severe fines for endangering public welfare.
I site today's 100 car pile up on the Pennsylvania Turnpike as evidence of the dangers of forcing employees to come to the office during inclement weather situations.

Only emergency personnel, or people who absolutely must travel, should be on the roads when the weather makes travel hazardous. The safety of the public is vastly more important than the losses incurred from one lost business day.
