Besides the FMLA, arent you eligible for short-term disability at the very least????
I know where I work, after 4 weeks out, it becomes short-term disability, AND does not cut into my sick or vacation time. It is paid at 100% for 4 weeks, then 70% each week after, up to 12 weeks ( FMLA) This may be different from company to company, but for sure.....know and exercise your RIGHTS
