I was hired at the company in December, 2007. In April 15, 2010, I had open-heart surgery. I informed my employer in advance and requested an indefinite leave of absence depending on my recovery. I ended up missing 5 months. I worked from home for a month and a half, but was told I could no longer do that in July. The company's employee manual says medical leave of absence may be requested and granted for up to 6 months, but personal leave of absence can only be for thirty days. I was told by my employer that since I left the company for more than thirty days, all my time with the company for leave accrual purposes, pay, etc. started over in April, 2010. How can this be right?
