My wife had cancer in early 30s and it was a punch to the gut for us both. It was actually a very survivable thing but she had to go through some extreme treatments. Regarding work, she did some paperwork and went through the HR stuff for most but there was a lot of "off the books" type stuff that fell into her leader's "who cares about this place, put your health first" policy.
I wasn't even sick and honestly didn't even get any additional stress other than worrying for her (we had no kids yet, her mom was helping her daily) and my ability to perform was shot. I could barely keep a thought in my mind or give a shit about petty work "problems". Probably for a solid 6-12 months. The first 3 months were and still are a complete fog. I never officially told my company HR, but my leadership was extremely supportive and I basically just phoned it in for that year. I did no significant work and offloaded most of my responsibilities to others so that I was not a key part of anything.
When you go through something like this, you start to learn how much other people have gone through as well. They feel obligated to pull you aside and share their story and how things turned out for them. Often positive stories but obviously not always. But generally people treat people in these situations how they'd like to be treated as, it could happen to any of us.
Just wanted to throw some positive perspective out there. Amazon is a well known shitty place to work for humans. I'm not surprised by this article. I dodge their phone calls like many of you and encourage you to get to know your coworkers on a deeper & personal level. They are a more important part of your life than you may realize and will help carry you through some really rough spots if you let them.
