Add a new Record rule;

======

Name: Limit employee view by company (or something like that).
Object: Resource Detail

Access rights: Check All (R/W/C/D)

Rule:

[('company_id','in',[user.company_id.id])]

Global: check

======

That should fix it.

Thanks Ray, I'll check that out.

All the employees are set up within departments in their respective companies.

Thanks

Tony

company_id exists on Department, not employee.  

Is each Employee assigned to a Deparment at a different company?  (Have not tried, this is just my suggestion).

Usually when you see 'all records' in a multi-company scenario, it is because company_id is False.
