Show Content Type Fields from a entity reference
To show the Parent info (Company) through Child nodes (Employee) you need to add the Relationship for the Entity Reference field that is connecting the child to the parent. 

Once you add that Relaionship you will be able to add the fields from the Company CT. Those fields must use that Relationship to show the Company info, otherwise if you don't select the Relationship for a field it will show the original (Employee) info. 

So after you add the Relationship for the Company ER field (that is on Employee CT), you will be able to add the Logo field to your Views, and that field will use the Relationship you've just added.
