However, this is the worst advice I have ever read. Good experiences should not be translated into advice. Your employer is not your friend. You may be lucky enough to have friends who share the same employer, but at the end of the day you are employed by a business, treat it accordingly.

Here's how I handle quitting in a remote world (as a cold hearted jerk/machine, aka a business). I give my two weeks notice, and start my new job the same day I give notice. I effectively have no real work to do the last two weeks at my current job, and have a nice relaxed onboarding at my new job. At the end of the two weeks I collect two paychecks. Rinse and repeat every 1-2 years to collect a 30-40% raise.
