How to interpret “and”

Question

Please be respectful to fellow employees, partners, and others who work with or on behalf of XXX and XXX’s legitimate business interests.

In the example above, I am not sure if the bold part applies to "others".

I'm not sure which one is correct among two:

(others who work with or on behalf of (XXX and XXX’s legitimate business interests)) - If I interpret this way, it also implies "others who work with XXX's legitimate business interest", and I think it sounds awkward

or

(others who work with or on behalf of XXX) and (XXX’s legitimate business interests) - I think this doesn't make sense, because the verb is "be respectful" and if I interpret this way, it becomes "be respectful to XXX's legitimate business interest", which sounds awkward.

Answer 1

This sentence is asking you to be respectful of 3 groups of people:

1. fellow employees
2. partners
3. others who work with or on behalf of XXX and XXX’s legitimate business interests

It makes much more sense for and XXX’s legitimate business interests to refer to others.
