Redirection to Organization Dashboard in Employer of Relationship
No need to redirect.  


Make sure that in the employee's Contact > Relationships tab that by Permissions it is checked that the Employee can View and Edit the Employer Contact.
When the Employee logs into their dashboard, scroll all the way to the bottom and you will see a Relationship section showing "employee" as Employee of "Employer". Over to the right you will see Edit Contact Information &amp; Dashboard. This will allow you to access the "Employer" Dashboard.
