No. Provided that it's related to aeronautics, Mr. Volpe, you're right; they will all be governed by an SMS. However, I don't want to mislead you. If in a company like a food caterer, like Cara, for instance, an employee decides to report, those guys are not covered by an SMS.
I just don't want to mislead you, because there are many other companies in an airport working and having contracts with the air operators.
