I'm sorry, no one who hasn't worked in a hurricane prone area should be weighing in. These cries of "the hospital must evacuate!!" just don't make sense when there may be nowhere for the patients to go, if the whole state is under threat.
For those of you unaware of how it works down here:
If you work full or part time at a hospital in Florida, by June you are assigned to some sort of hurricane "team." Either pre storm (some hospitals don't do this one), during storm or post storm. If you are during you are expected to stay at the hospital from about 8 hours before landfall until the local government has sounded the "all clear." If you are post, you are expected to report to the hospital immediately after the "all clear," therefore if you are on post team you may NOT evacuate. If you do, or don't show up when you are assigned to, you will be immediately fired. I've seen half a dozen nurses at multiple hospitals fired for this.
HOWEVER, if, like the OP, both you and your spouse may be needed to work the storm, or if you are a single parent or the sole caregiver of an elderly parent, special needs family member, etc., you APPLY FOR AN EXEMPTION from your employer. Of course, this must be done in JUNE, not when the storm is bearing down. This is the crucial step the OP missed. Knowing her husband would have to work, she should have applied for an exemption for herself, or for her husband, so one of them could care for the child or evacuate.
If the OP is a new nurse or new to Florida, or started work there after June, ok, maybe that's why she didn't know. But those of us who live here are shaking our heads at the hysteria of 'omg I have to report to work when I said I would?!"
