Things are heating up: More than 100,000 railroad workers in the U.S. could go on strike

State businesses are sounding the alarm and warning of a "disaster" if a mass strike by railroad employees begins. It could be the record since 1992.

The U.S. economy is heavily dependent on rail freight, and a shutdown could cause significant problems in many sectors.

The damage to the U.S. economy could be $2 billion a day. Most likely, the state government will intervene in the situation and help reach a compromise. However, the risks still remain.
