There most certainly is a rule that states NRSAs shall not engage in behavior which is disruptive towards revenue customers - that rule covers a wide range of examples, from talking over customers, speaking loudly when revenue customers are trying to rest, insisting on seat changes, insisting on meal choice, stealing upgrades, etc etc.

There has always been a requirement that NRSA be essentially invisible and unknown to revenue customers and have absolutely zero priority with regard to inflight service or product offerings.

The rule is pretty general and fairly easy to follow for those who know how to act professionally.

I am really shocked at the assertions that NRSA should be offered a form of 'equivalency' with revenue customers. This has never been the case - on any airline - except where employees are acting out of control and bypassing NRSA rules to take care of each other - something that happens far too often on United with management far too often looking the other way even when incidents are complained about.
