do you think that your schooling background and employment experience do not have these basic elements present with in “work culture”

No, I think those elements very much reside in the way I learned to approach work, even growing up in multiple countries as I have. It's only since I've hit a later stage in my career and sat back to assess the health impacts it's had that I've been more willing to sit up and advocate for myself and my colleagues. I think it might have something to do with how aggressive I can be about workers' rights haha. I recognise though that I'm privileged with a sought-after skill set and so I'm usually pretty insulated from retaliation for that, because I can't be easily replaced.

Thankfully, my current employer is a firm believer in taking care of their people and treating their employees fairly, which is one of the reasons I've stuck around here. The contrast though just makes this kind of shit from larger orgs all the more infuriating, because if my tiny company can treat its employees well with such a comparatively tiny revenue stream, then FAANG can too and they just don't. Bastards.
