Worrying About "Worrying"

I have recently read a number of articles, mostly on the economy, that used the word "worrying" in a way that I'm not sure is correct. Similarly, I've seen and heard the word "concerning" used in the same, possibly incorrect, context.

"She is worrying about the safety of her job." No problem here.

"The current job trend is worrying" (substitute "concerning" and you have the same issue). Are there such words as "worrying" or "concerning" in this context?

If not, should I care or is this just the way language evolves?
