"SOP can have all kinds of complete rubbish"
Read you 5 by 5. Problem here, as samotnik said, is that AENA is checking regularly for any ATCO doing anything out of the rules to punish them. They have their hands tied (it is my understanding that the employers have, on accasion, intruded on the operations and demanded from ATCO's to do things against the rules, threatening with disciplinary action if they wouldn't follow their command...but not protecting the staff if they would either since the rules still said it couldn't be done...so a very weird situation all in all).
