@She Cat... Absolutely agree with you. It's blameshifting, cowardly, assholery. 1 month into a process that takes 6-12mo, just a few days post-OP, haven't even started radiation yes... And present an impossible ultimatum (your turn to take care of me, now, or we should get a divorce)??? I am beyond furious.
@Snowflake... All the work you have done doesn't vanish in the face of monumental stressors & emergencies. You take care of the emergency in front of you, and then can look behind you, again. Like driving a car. Sometimes you need your eyes on the road you're driving.
You can also take a sick-day (or several) while you're *sorting out* your FMLA. You don't have to sort FMLA before you take time off. Your GP can write a note for today/tomorrow/etc. while you get in contact with your radiologist.
ETA... In FACT... Most cancer care clinics have a few dedicated social workers (aka that's all they do, is work with that clinics cancer patients and their families, and are in no way responsible for the rest of the hospital, because CancerCare is a huuuuuge job). Whose JOB it is to provide case management & streamline resources / getting needs met for patients. Including FMLA & doctors notes (as well as insurance, housing, groceries, counseling... Pretty much any resource a patient needs). One reason you may be running into trouble is that you're trying to do this all yourself, instead of the more normal route of having the clinic social worker advocate for you.
