Comment I found another sub discussing this:

He was hired in late 2011. He then couldn't start work with them at the start of 2012 because of the cancer. He than said he got better enough to work from home for "about a year" until early 2014 when the cancer came back, and he had been off work since then before being fired in February 2015. What's more, they even paid him his salary for the year after the cancer came back. This is far, far above what a company is obliged to do not only in the US but any European jurisdiction I'm aware of. He worked for under one year in an over three year time span. You do not have to keep a job open forever for someone with a chronic illness, never mind pay them. In the UK, for example, you cannot fire an employee over sickness, if the sickness is medically documented, up to a period of three months. After that, you can let them go. He went at least four times over the UK standard, twice. The employer in the UK also isn't obliged to pay you your full salary while sick but only a statutory minimum of £88 ($137) per week for 28 weeks. They appear to have paid him full salary for at least a year. It sucks for the employee, but there comes a point where an employer has to be able to say, sorry, but you are simply too sick to do the job. And someone who was only able to work remotely for under 12 months out of 36+ is too sick to do the job by any reasonable analysis.

TL;DR:

It seems the truth is that Reddit actually went above and beyond trying to keep Dacvak as an employee, paying him full salary, way more than they were obligated to (in any country) while he was sick and unable to work.

You're making fools of yourselves by making this an issue.
