My local onc offered me disability leave at my first meeting - with the added comment "but I suspect that if you can't work through this, you will go crazy."
My co-workers and my bosses (mostly) have been terrific. In 2004, I was not at a job grade that was usually issued a laptop - but a vice president who had formerly been my site's director called my 2004 bosses, told them he'd authorize home broadband and telecommuting and whatever else I needed, that he'd carry the costs on his executive level cost center, and told them to build me a laptop right away. I already had 5 weeks of vacation and we get paid sick days, but I worked all of my non-chemo infusion days - either on site or from home. I couldn't work my infusion day 1 - it was a 9-hr day with a slow oxi infusion and avastin. I took vacation for NYC medical consults because I felt guilty - when I had to travel to NYC for monthly infusions, that changed to 'working off site' and I taught at the NJ site as part of my NYC trips or worked from my brother's home office on my company laptop.
My company builds cancer drugs. My co-workers have always been beyond supportive - offering second opinions, reading my scans, interpreting my bloodwork and more. As my original bosses started to retire, management's attitude changed a bit - I lost out on project management gigs and then ultimately promotions because, hey, I might die. Of course they couldn't *say* that, and couched it in phrases like "we want to spare you that kind of stress and utilize your skills more efficiently." But then when the last of those managers retired last year, she called me up and apologized to me - said she realized in retrospect that she had been holding me back and that I didn't need that kind of 'protection.' Nothing actionable, you know - completely she-said/she-said hearsay, but at least I felt better that I hadn't imagined being pushed aside by some of the managers.
The first operation, I took short term disability and came back to work after four months, and continued 11 more months of chemo. The second operation (liver resection), I ended post-op chemo after 3 months and went back to work from STD after five month. The third operation (recurrence), I stayed out for 5 months, 3 weeks and 3 days of my six month STD leave.
Chemo was wiping me out - and I still had two more months to do. I did it - but I *know* I was not at the top or even the middle of my game on many days. I worked from home 3 days out of every 14 day infusion cycle. I made up some time on the weekend. I wouldn't have gone back at all - seriously considered long term disability at that point.
But in Sept. 2008, I knew that I only had 26 months until I turned 55 (November 2010.) I had 22 years invested in my company retirement plan. And in that plan, the difference between retiring before you are 55 and retiring the day after your birthday is enormous - for me, $1200/month. I figured I could tough out anything for 26 months. I have four more months to go - and I will get both severance because the site is closing, and my retirement. So for me, that was a good choice. I had to try. And I knew that I could always go on SSDI if things really became too hard. This last year has been a bear. I told my bosses that I was going to work 1 day from home for the rest of the year, and that may increase if working conditions don't improve. At this point, if they release me early without severance, it would be actionable because an active severance agreement is on the table. They aren't taking any chances.
But if you can take disability without compromising things like retirement plans or health insurance or the job itself, and you can take the time to focus on you and get better - DO IT! One big thing I have learned - you are not your job, or maybe - you are MORE than your job.
