I had a surgery last Dec 2016 and was expected to miss work for 6 weeks. I initially used my vacation and sick days (4 weeks total) and had signed a medical leave form. However, due to the findings after surgery (cancer diagnosis), I had to miss work for 6 months for treatment. I submitted another medical leave form submitted it on Jan 2017. At that time, our HR director said that if I exceed the 12 weeks FMLA, they will "discharge" me from the company. Twelve weeks passed, I was thinking that HR has "discharged" me already. About last week of June, HR called me, offering a position but I politely decline for I have just finished my treatment, have to go through tests and thought that she has discharged me. She said "let me know when you want to be discharged". I don't know how I reacted at that time but I was puzzled. But due to what I was going through medically, I've never had the chance to follow it through. At this time, HR hasn't contacted me yet again. I am just wondering. why was it up to me whether she would discharge me? She never also never mentioned if I have to provide any additional paperworks from my doctors. Should I give a resignation letter? Or what should be my next step?
