I wouldn't consider it bad practice to do as outlined below. I would,
however, add an indication in the USER table as to what Type of user
it is -- an Administrator, a Client, or Staff. Without such a Type
field,
you're gonna have to check all 3 tables to see which it's in. The Type
will point it at a specific table.
