I was planning on retiring on February 28, 2022, but might extend that date by three months. My company (and every other one in the USA?) was required as of 1993 to recognize the Family Medical Leave Act. In my case, it allows up to 12 weeks of unpaid leave from work to take care of a sick family member or yourself if you are ill. The act also requires the company to maintain your healthcare insurance and to give you an equivalent job when you return to work. My plan could be starting the year on FMLA, then work 2 weeks, take my 6 weeks of vacation and retire.
I can purchase retiree healthcare from my company, but the premiums and deductible are much higher than active employee healthcare insurance. The FMLA will allow me to maintain my current healthcare into "pseudo-retirement" for another 3 months, then I'll go for sure. Kind of milking the system a little bit, but it's their system so I'll take advantage of it if I can.
I may be taking some FMLA this year too as my mom has cancer that is progressing. She has spots on her pancreas and L1-L4 vertebrae. She has a fantastic attitude about it because of her faith. If things start going south quickly, I'll take 3 months off from work without pay to be with her.
Another option a cousin of mine told me about (but I haven't investigated well) is the Affordable Care Act. If I understand my cousin correctly, he is delaying SS until 66/9 months for his full share. He receives no pension from his former employer. He and his wife banked enough money after taxes to live on until they both turn 65 and file for Medicare. In the meantime, they are technically paupers and qualify for health care through the Affordable Care Act. He just has to make sure they don't exceed something like $36,000 or $38,000 a year in unearned income, of cashed in 401K bucks.
