No problem
If the employee are all users, you can set the Key field of the EE table to be the userid and then make a relationship to the details table using a reference field on the right side of the relationship of the field I like to call [Current User] with a formula user formula of
User()
If not all employee have userid�s or for other reason you are unwilling to change the key field, then you can make a Sync table of selected fields from the EE table and set the Userid in text format ( it will sync across as text) to be the key field. Only bring across EEs with a userid.
Then make a reference field with theformula
ToText(User())
To make the relationship.
