It is one of the bad side effects of the 'Work from Home' trend in blue collar jobs.
No one is concerned when they don't see or you don't come in for days.
I knew of several co-workers over the years that didn't show up for work and someone stopped by their home and found them dead.
These days it is common place not to see someone for days or weeks while they work from home.
One of my former co-workers wives does medical approvals from home and only has to 'go into the office' a couple times a year.
You're exactly correct. I've had four co-workers who were found dead in their homes when they didn't show up in-office or online after a few days.
One was found in bed (died in his sleep), two at their desks in their home offices and one on the floor in her kitchen. All four empty nesters and divorced/not married.
As a divorced empty-nester myself, it's one of my fears that I'll pass away @ home and no one will notice for awhile. Many of us are 55+ and have started our own informal network of checking up on each other daily to make sure we're ok. If we don't see each other for a day we know to do a health & wellness check so at least someone finds the body reasonably soon.
Kinda a morbid outlook there, but it's the reality we live in now.
