Agreed as David and Mamacita mentioned. I see no chemo in treatment?
Employment, Income, and coninuation of Medical Insurance is a big concern, and how will one get these if no longer able to work, even for short term, is not often thought of. It was a big concern for me, being single. FMLA is only for job protection, but is not compensation for income. See about short term disability, which is 26 weeks, which can be extended to long term disability, if your employer has it. Mine also had managemny compensation for your salary, depending the years you worked, and mine was 75% of my salary, plus the Short term disability, so I lost no income, and I needed it because I could no longer work after my first treatment. Find out what your benefits package(s), contracts are, when forms, type of forms are required, and by what dates, and what updates are required, and doubt many will educate you, even HR. I know people who lost their jobs not following the rules, no updates, and extended their FMLA by one day by sickness or no sickness, its only business! I had to bring HR's "attention" at every step, by bedside in the hospital, what were my entitlements were, and knew them like a book, and received what was due, and wasn't asking anyone for sympathy payments, but only what I was entitled too. I even called the U.S. labor department, who made a three way conversation, and telling my employer I was right lol. When I was going through treatment the social worker even said to apply for SSDI, just in case, and laughed to myself. I wound up having to apply 7 months later.
Good luck
