Ask HN: Maximizing sick benefits in Silicon Valley

As a sedentary Silicon Valley guy with 25 years sitting in the damn chair and writing the damn software you're using right now I find myself facing having to take time to deal with newly diagnosed colon cancer. But I'm really not bitter, I'm just not sure how to proceed with maximizing the time that I've got on the corporate books.

This is a huge company with great benefits. I've got 228h vacation time (!!! Haven't taken any in some time and it's about to pin anyway !!!) and according to my time off page, 625 hours of sick time accrued.

The corporate hr page says that medical leave of absense may incorporate those times, but my question for my hacker brethren is how I can best approach hr and management to take best advantage of the corporate benefits.

I know that every company is different, but any advice is greatly appreciated.
