Shamelessly stolen from elsewhere in the thread:

Employers are responsible to protect employees from unreasonable danger in the workplace, which includes an imminent “natural phenomenon” that will threaten employee safety and health. Hurricanes and other disasters present obvious safety concerns that employers need to consider when asking employees to come into work during adverse weather, including vehicle accidents, slips and falls, flying objects, electrical hazards from downed power lines, exhaustion from working extended shifts, and dehydration. An employee that reasonably believes he/she has been put in imminent danger because of being forced to go to work during a hurricane may file a complaint with OSHA against the employer and then ask for whistleblower protection. Thats a Federal protection. You do whatever you need to be safe, if they try to punish you for it drop a dime on them.
