Losing/Leaving Employment Customs

Why is losing a job so difficult?

Being told by my neurologist that I cannot work is honestly devastating. It's also depressing and infuriating.

It just makes me wonder why it's so horrible of an environment in corporate settings. Why is it customary to give a two week or more notice? Are we given the same courtesy if we're let go? No, we aren't and being let go can be devastating. But this doesn't seem to matter and the standard expectation is only on the employee, NEVER the employer. I wonder why that is.

Why are we okay with it?

It's like that ridiculous video posted by a YouTube auditor who was assaulted. The inept or corrupt police officer Hendershot responded to the auditor's account of the assault by asking if he'd told the culprit that he did not wish to be touched before he assaulted him.

I couldn't believe he said that! I wonder, at some point do the police expect any law abiding citizen to just walk around, telling everyone in their proximity not to assault, rob or rape them? I mean, I feel it should already be implied in society, right?

Does that then mean that we should inform our employers not to fire us? There's other customs that are considered appropriate or just customary at work. But it seems to me that regardless of the setting being corporate or not, this two week rule is a customary expectation. But it just seems so hypocritical to me that the same expectation is not expected of our employers before they potentially put us in a hardship.
