Usage "over" and "about" in some expressions

[Pierce111]

I was convinced that "over" is used with nouns (e.g. anger over smth, strike over smth, worries over smth, talks over smth) and "about" is used with verbs (to be angry about smth, to worry about smth ....). But recently I heard a few times that "over" was used with nouns (to be angry over, to worry over). Is it ok? Can I replace "over" with "about" (and reverse: "about" with "over") in such sentences (with nouns and verbs) when we talk about the cause of some activity or thing?

Particularly in newspaper headlines one may often find 'anger/worries over...', but in daily use 'about' is at least equally common. Regarding the verbal constructions, however, 'over' would not be the natural choice for BrE speakers (nor, I believe, for AmE speakers...)

With respect to AmE usage, I concur.

So using "about" in each such case seems to be the best solution?
to worry about ......
the worries about ....

It's best to use "about" unless you're sure. Your first post gives a lot of different examples. It's possible to say "I worry over/about my finances", but we don't say "He always talks over the weather."
On the other hand, you strike "over" wages and conditions, not "about" them.
