for which they get

[daruk]

Hello, forum gurus!

A.
But if you had to hire people of the same caliber they would cost you an arm and a leg. Rather, people in these communities are happy to give their time to society at large (for which they get the same social benefits we all get from helping a friend paint a room). What can we learn from this that is applicable to the business world?

*** A and B are same, except that the ( ) is used or not.


1. What does the which refer to, in A and B?
their time? or to give their time to society at large

2. How about if for which is replaced with from which?


Many thanks, dear English gurus, in advance.
Partial explanations would also be greatly appreciated.

The "which" refers to the experience of volunteering their time, presumably. "From which" seems an acceptable substitution in this context. (It's not particularly well written, as far as one can tell from this tiny excerpt. "To give their time to society at large" is a weird phrase conceptually, though it is grammatically acceptable.)

I see.
This helps.
Thank you so much!
