Taking care of my mentally and physically disabled mother is impacting my ability to maintain consistent hours at work. Are there alternatives that can provide some sort of back up assistance (such as disability) that can aid financially if i am needing to take extended FMLA w/or/w/o pay? I need to take leave for a good amount of time in order to get her established and her health stabilized. I know I can take FMLA, i think, but I need more info on any options, either federal, local, employer based, or other programs or coverage types that may be able to temporarily help with my compensation until I am able to return to a steady work schedule?
Your mother appears to have many health issues, and there's no assurance that she will stabilize - or is there? So many people come to this forum after doing exactly what you're contemplating, and the stories are horrendous. They quit working, devote themselves to mom, she never gets well, and they're stuck. When they want to return to work, they can't get a job. If they've moved into mom's house, they may soon be homeless. Also, moms are not always grateful. They start blaming the onsite caregiver for the mess they are in.
If you can place mom somewhere that professionals can care for her, you will both be better off than what you're planning.
FMLA, do you realize that you can take the time in increments?
Medicaid, if Mom fits the criteria, she may get an aide for in home care. Would depend on her mental illness if this would work. Call your local Office of Aging for help.
You are better off keeping your job and finding resourses for Mom. There really is no program that will pay you enough to care for Mom.
