does an employer have a legal obligation to negotiate in good faith when hiring an employee?

I was being recruited by a large medical firm in Baton Rouge prior to hurricane Isaac. I let the recruiter and my potential boss know my house was flooded by hurricane Isaac but they still wanted me to go to work for them immediately. I quit my job and went to work for them. Approximately a month later they fired me when I let them know I was having trouble getting back into my house. I requested leave of abscese or some time off to deal with the personal issues related to the storm such as getting a roof over my families' head.
