IME bullying -- actual bullying, not power contests or nasty office politics -- isn't even remotely normal in office settings.

Anything physical is de facto serious and should be dealt with via adults and not between children; at least in my bubble, physical violence between school-aged children is rare and taken very seriously. A bully physically harming other children would receive a serious punishment, the parents would be in the loop, and the school counselor would be heavily involved with that child for the remainder of the school year.

Anything systemic and sustained, or targeting immutable attributes, is also de facto serious.

It's possible that things are different in your social environments, but "bullying" as I understood it as a kid is no longer even remotely socially acceptable.
