Don't worry about the job!!! Although good on you for being so considerate. But you're about to CTB soon!!!!! Please don't let a stupid regular 9 to 5 job ruin even your final moments. The absolute worst that can happen is your co-worker or boss need to work some extra shifts. That is all. Its not like your co-worker isn't getting paid or anything. Take it as your co-worker now earning extra money. Especially for your boss, it is part of their basic responsibility to go through at least some risks for running a business, and covering shifts is really not that much of a huge problem at all. Shit happens. There could be lots of other things that could be many times worst for them as a business owner. As a business owner, they should have backup and emergency plans in-place, if not, then its a fail on their part. It is not all your responsibility. Its not your company in the end. You are not here doing charity work. Its a fair trade. You show up for work, and they pay you money. Now that you don't show up for work, they don't pay you the money. This is really nothing, compared to what you are going through. Its not like they assigned you a multi-million dollar project during these few weeks, where if you didn't show up the owner will instantly lose millions and become bankrupt overnight or homeless or something. Just think of it as you getting into an unexpected car accident, and are now injured in the hospital, or even some last minute serious sickness, so can't show up to work. But instead, your case is even more serious. You are about to die now!!! That is even more serious than cancer. It is time to finally WORRY and CARE about yourself for once. The fact that you are still concerned about them during a time like this, deep down, you have already more than truly done your part, whether they realize it or not. There is no perfect in the end. You should instead be proud of your kind heart. Just send them a last minute message/ email/ voicemail and make up a lie about an unexpected emergency of some sort, and don't show up to waste your final precious moments being a slave. They will replace you without hesitation shortly after anyways. Your boss is here to make money at the end of the day, and money has no feelings. All the best to you!!!
