I am looking for a word/expression that refers to the related area of someone's job.
I've thinking in
job field or
work field but I am not sure which one is more correct or if there is another different word that fits better.
Imagine the following sentence:
They both share the same _____
How would you fill the empty slot?
There are other sentences where
industry sounds good to me. For instance:
I don't like that family, they all work on the computer industry.
Cars industry also sounds good, but what about
laws industry? That sounds weird.
So, is there a more general word? Can someone tell me a solution for each of these cases?
