Two options

1. Create multiple member tables
member_student,member_faculty,member_staff and
issues_student,issues_faculty,issues_staff

2. Create a new column called flag in both the tables like
Create table member ( memberid iNT, Flag Char(1) --S - Student,
F- Faculty, T - Staff)

Primary Key (flag,memberid)
Create table Issues (memberid INT, Flag Char(1) -- S - Student, F-
Faculty, T- Staff)
Primary Key (flag,memberid)

Now Reference two tables with flag and memberid.

If you want to refernce member table with student,faculty,staff you
need to handle in trigger
