Can I use taxonomy term as relationship in view?
You can create a view of jobs:



with a taxonomy term relationship on your field_company_name in order to show the taxonomy term name and any other fields it might have.

In order to show the email of user that is referenced from the taxonomy term you will also need a relationship (via the field_company_name relationship) on user so that you can access the user fields (eg email). The option to add this relationship will now be available from the relationships list, if you filter by user.





Sidenote: You may want to consider using an additional email address on the user for this in case the user does not want to receive job applications at their own personal email address, but wants to use their personal email address to manage the account.
